Presenter: Auri Rahimzadeh, Owner, Auri's Ideas
Description: A walkthrough of an app I recently wrote for scanning CoViD patients in my city. They needed a way to marry a patient and kit without manual data entry, and they needed it in 24 hours for the free CoViD tests starting that week. I'll explain the requirements gathering process, the initial designs, the Xamarin mobile application, how we mostly avoided back-end development, and how usage analytics and the first week panned out.

A
A
All
right
great
well
welcome
to
Indies
Ameren.
My
name
is
Ari
Rahim
Judah.
You
can
just
call
me
Ari
and
we
got
Greg
del
Santo
on
the
line
from
Sandy
another
one
of
our
organizers,
and
we
run
our
meetup
on
the
last
or
the
fourth
Wednesday
of
every
single
month.
Recently
we've
been
doing
this
online,
which
has
been
great
it's
it's
brought
more
people
in
and
especially
when
we're
all
kind
of
locked
into
our
homes.
It's
it's.
It's
been
good
to
bring
people
together,
so
I
hope
you're
all
staying
safe.
A
Some
thanks
to
our
sponsors
sandy
solutions,
which
Greg
is
part
of
launch
fishers,
which
we
can't
use
their
space
because
well,
actually
they
just
started
allowing
people
to
use
their
space
again.
I
think
we're
gonna
be
virtual
for
at
least
a
few
more
months.
While
things
settle
down,
we
don't
wait
if
we
want
to
do
everything
safely
in
fraktur,
which,
if
you're
a
xamarin
developer,
if
you
haven't
heard
of
it,
you
should
phenomenal
software.
A
It's
it's
a
if
you've
ever
used
resharper,
you
know,
resharper
does
great
things
for
development
productivity,
em
tractors
like
that,
but
specifically
for
xamarin
well,
mostly
for
xamarin
and
then
of
course,
ref
debug,
which
is
very
cool.
You
can
replay
your
entire
debug
session
and
find
all
your
exceptions
and
so
forth
and
see
the
exact
state
of
the
application
when
the
exception
occurred
and
the
entire
flow
of
the
application
after
you've
run
it.
So
you
don't
have
to
set
breakpoints
everywhere.
A
B
So
sonic
solutions
were
an
IT
staffing
agency.
We
also
have
a
managed
services
side
of
our
business
that
works
with
the
city
of
Indianapolis,
the
state
of
Indiana
and
different
other
municipalities
here
in
town,
so
we're
based
here
in
Indianapolis
we're
about
a
block
from
Bankers
Life,
which
is
where
the
Pacers
they
D
and
the
Pacers
play.
So
we
are,
we
do
a
lot
of
different.
We
do
project
managers,
developers,
programmers
lots
of
different
roles
that
we
fill.
B
We
work
with
clients
like
IU
Health,
with
the
Colts
Eskenazi
health,
all
different
sorts
of
companies
right
here
in
central
Indiana.
So
if
you
are
looking
for
a
new
role
feel
free
to
send,
you
send
my
resume
and
your
resume
to
me.
I'll
put
my
email
and
contact
information
in
the
in
the
notes
but
happy
to
be
here
happy
to
sponsor
it,
and
thanks
viii.
A
A
B
Right
yeah
right
now
we
have
a
few
but
they're
like
ash.
There's
a
SharePoint
developer
role.
We
have
open
there's
a
few
other
internal
roles
that
are
on
our
website
as
well.
I
can
link
to
that
and
in
my
post
as
well,
but
we
get
different
roles
all
the
time.
I'm,
not
gonna,
say
we
get
xamarin
roles
every
week
we
don't,
but
probably
every
every
quarter.
We
may
get
one
or
two
okay.
A
Yeah,
oddly
enough
I
get
a
lot
I
see
a
lot
of
people.
I
hear
a
lot
of
people.
Ask
do
you
know
any
xamarin
developers
or
you
know
any
like
specifically
Android
or
iOS
developers,
more
Android
than
iOS,
and
it's
funny
because
I'm
like
what
he
just
going
to
learn,
xamarin
and
then
you'll
have
a
good
feel
for
both
and
I'm,
seeing
more
xamarin
opportunities
than
specific
platform
opportunities
in
Indiana
I.
Don't
know
what
what's
like
elsewhere,
but
it
has
been
pretty
interesting
hearing
that,
let's
see
there,
we
go
Greg's
messaging,
his
email
address.
A
Cool,
so
can
everyone
see
my
my
slides,
of
course,
I
can't
Greg
you'll
have
to
let
me
know,
because
I
can't
see
the
chat
now
because
I'm
running
on
my
single
screen
mode
yay.
So
hopefully
everyone
can
see
this
thanks
for
joining
tonight.
A
little
bit
about
me,
my
name's
Ari
Raheem's,
Duda
and
I
own,
a
small
little
consulting
firm,
called
Ari's
ideas
and
then
I'm.
Also
a
software
engineer
at
valorum
reply
so
get
to
do
a
lot
of
fun
stuff
across
both
of
those
most
of
my
mobile
app
work.
A
I
do
through
our
Rhys
ideas
by
Brina
I've
written
a
lot
of
apps
and
for
those
who
know
me,
I'm
a
public
I've
written
a
lot
of
public
safety
apps
one
of
those
was
acquired
last
year,
and
you
know
just
if
you
get
a
speeding
ticket
in
the
state
of
Indiana.
I
wrote
that
software,
if
you're
reporting,
non-emergency
crime
in
Indiana
I
wrote
that
or
in
various
cities
around
the
u.s..
Actually.
Now,
because
that's
expanded
wrote
a
lot
of
pro
bono,
software,
all
xamarin,
so
you
know
Greg
and
I
and
Tim
we
put
together.
A
They
are
not
not
Jim.
I'm
sorry
I'm
thinking
of
the
Indy
got
net
consortium.
We
we
brought
together
or
we
started
the
Indies
Ameren
meetup.
You
know
because
there
seem
to
be
a
need-
and
you
know
not
really
it
wasn't
being
fulfilled
and
in
in
in
in
Indy,
for
these
mobile
developers
so
happy
to
be
here
today.
We're
gonna
talk
about
this
app
that
I
built
for
the
city
of
fishers,
where
I
live.
That's
for
a
Kovac
patient
scanning
app
so
before
we
get
started,
though,
feel
free
to
ask
questions
at
any
time.
A
We're
we're
gonna
cover
a
bunch
of
things
tonight.
So
one
is
how
the
app
was
built
like
requirement
specifications
so
an
overview
of
it
getting
it
built.
We're
definitely
going
to
look
at
some
code.
If
you
have
questions
about
the
code
or
you
know
different
approaches,
let
me
know
how
we
rolled
it
out
and
the
lessons
learned
there,
so
we're
gonna
cover
all
of
that.
So
a
little
bit
about
what
Fisher's
is
doing
so
Fisher's
is
a
city
of
around
90,000
residents.
A
I've
lived
here
a
really
long
time,
like
back
when
we
had
yeah
two-lane
roads
and
and
now
we're
one
of
the
top
ten
places
to
live
in
the
United
States
so
to
live
and
raise
a
family.
Fisher's
was
rated
by
Money
Magazine
when
the
top
ten
places
to
live
and
multiple
years
in
a
row
now,
which
is
it
was
just
funny.
Considering
that
you
know
there
was
nothing
here.
It
was.
It
was
cornfields
and
like
a
little
recreational
park,
but
we've
grown
tremendously.
A
We
got
a
very
progressive
mayor
and
with
COBIT
we
kicked
off
a
city
health
department,
so
moved
from
the
county
health
department
to
having
our
own
city
health
department
and
we're
offering
well
I
say
we,
you
know,
but
fishers
is
offering
free
covent
testing
to
all
90,000
residents,
so
no
charge
and
they're
cutting
a
deal
to
any
businesses
here
that
if
they
want
to
have
their
employees
tested,
even
if
they're,
not
a
resident
of
fishers,
they
simply
pay
the
same
price.
That
Fisher's
pays.
A
So
no
markup,
the
the
goal,
of
course,
is
get
people
tested
and
do
contact
tracing
because
contact
tracing
is
what
really
helps
control
an
outbreak.
If
you
haven't
heard
much
about
contact,
tracing
or
learn
much
about
it,
I
suggest
you
look
it
up
and
it
kind
of
proves
itself
out.
If
you
read
about
it
now,
you
might
have
seen
there's
there's
a
painful
method
of
testing
perc
Ovid,
where
they
basically
touch
the
back
of
your
brain
with
a
really
long
q-tip.
That
is
not
the
method
that
fishers
uses.
A
They
do
a
shallow
swipe,
I
think
it's
what
they
call
a
shallow
swab.
Hopefully
this
doesn't
look
gross
as
I
point
at
my
nose
and
it
doesn't
hurt
it's
it's
a
little
annoying
because
it's
like
15
seconds
of
them
running
around
the
front
of
your
nose
and
then
you'll
have
each
nostril
when
two
with
two
toothpicks
or
it's
not
too
big
q-tips,
and
then
they
break
it
in
half,
stick
it
in
a
vial
and
then
that
could
sent
off
to
the
lab.
A
So
the
way
this
works,
though,
from
5,000
feet
up,
is
you
register
online
and
they
ask
you
a
bunch
of
questions
you
know
figure
out
if
you're,
high-risk
or
not,
and
then
after
you've
filled
out
that
assessment,
which
is
just
another
word
for
a
survey
you
receive
a
patient
ID
and
that
patient
ID
comes
to
you,
and
this
will
be
interesting
later
in
the
form
of
a
really
hard
to
read
jumble
of
characters.
It's
like
12
characters
or
something
and
a
QR
code.
That's
supposed
to
represent
that.
A
Then,
at
the
scheduled
time
you
scan
in
you're
assigned
a
test
and
and
then
you
take
the
test,
so
they
basically
you
drive
up.
They,
they
scan
your
QR
code.
They
grab
a
kit
out
of
the
box,
scan
that
they're
supposed
to
scan
that
label
in
and
then
those
are
tied
together
and
then
you
receive
your
answer
as
to
whether
you
have
kovat
or
not
within
three
business
days.
If
you
don't
have
Kovac
yay,
if
you
do
have
Coban,
they
will
definitely
reach
out
and
start
the
contact
tracing
process.
A
The
the
problem
is
this
part
right
here
didn't
exist
when
this
process
started
that's
a
problem
because
when
they
decide
to
do
this
and
I
got
a
call
which
I'll
get
into
in
a
moment,
we
have
like
a
day
to
really
get
this
going.
So
this
is,
let's
see
on
a
Saturday
morning.
I
get
this
email,
I
mean
my
event
Saturday
afternoon
again,
email
from
our
city's
IT
director,
hey
this
this
step.
Three,
this
one
right
here
it
doesn't
exist.
Do
you
know
anyone
who
could
help
us
make
this
work
and
I'm
like
I'll?
A
A
A
bit
kind
of
like
I,
already
had
a
bunch
of
the
scanning
code
already
written,
which
was
good
key
takeaways,
were
they
can't
have
any
data
entry
errors,
because
if
you
mess
up
getting
the
app
or
probably
the
the
patient
ID
associated
with
the
the
test
kit,
someone
doesn't
get
the
right
information
or
even
even
worse,
someone's
infected,
and
you
don't
know
who
they
are
scary.
Stuff
I
lives
are
at
stake
when
you
mess
up
data
like
that,
there's
a
lot
of
vendors
and
stakeholders
involved.
A
So
you've
got
the
the
people
handling
the
survey
you've
got
the
test
hit
manufacturer
you've
got
the
city
of
fishers,
you've
got.
You
know
our
own
health
department,
you've
got
me
yeah,
and
then
there
was
a
consulting
firm
involved
that
was
handling
the
overall
effort
outside
of
this
particular
piece,
which
was
an
unknown
at
the
time.
So
you've
got
six
different
people
and
you
got
to
get
all
this
stuff
working
and
basically
shipped
by
Monday
and
keep
in
mind.
A
I
know
nothing
about
any
of
these
people
when
I,
when
I
get
this
email,
but
anyway,
so
I
asked
Tracy
traces,
the
guy
who's,
our
IT
director
and
I
go
Howard.
Others
handling
this
task
because
the
state
we
used,
the
the
survey
was
from
a
company
called
Qualtrics.
They
handled
the
whole
survey
process
which
that
survey
ID
ends
up
serving
as
the
patient
ID.
How
are
others
handling
this
task?
A
Well,
they've
got
drive
up
bays
and
then
a
laptop
with
a
handheld
scanner
kind
of
like
you
got
at
Starbucks
and
a
web
browser
running
and
the
the
patient
ID
is
scanned
in
and
then
they
hand
enter
the
label
information
from
the
kit
and
then
click
Next
click,
Next
click,
Next
and
then
save
it's
potentially
fraught
with
peril.
I.
The
scanner
could
not
work.
They
there
I
think
they
might
have
been
printing
the
labels
in
real-time,
so
the
printer
could
break
down.
A
You've
got
a
laptop,
so
if
there's
a
power
outage
and
the
batteries
aren't
lasting
long
enough
now,
you
can't
process
your
patients,
it's
a
laptop
which
is
not
built
for
this
sort
of
thing,
I
mean
it's.
It's
unwieldy.
You've
got
to
have
a
table
for
it;
no
one
can
hold
it.
These
guys
are
in
bunny
suits.
Yeah
is
you've,
got
a
keyboard
which
you
know
tried
having
gloves
on
and
typing
on
a
keyboard.
So
if
there's
any
issues,
you
have
to
use
a
keyboard
and
possibly
a
mouse.
So
how
do
you
make
that
work?
A
Yeah
lots
of
bad
things
using
a
laptop
for
a
scenario
like
this,
and
so
my
my
thoughts
here
were
the
this.
This
has
to
be
a
mobile
app,
but
we'll
get
to
that
and
then
of
course,
given
all
of
this,
do
we
have
time?
Do
we
have
time
to
build
this
thing?
This
needs
to
be
live
by
Monday,
it's
Saturday.
So
let's
get
our
requirements
together.
A
That's
always
important
when
you're
building
a
mobile,
app
or
any
application
in
general,
but
let's,
let's
figure
out
what
our
definition
of
done
is
so
if
you've
never
scoped
out
an
app
or
an
application
or
a
software
development
effort
before
knowing
that
definition
had
done
is
paramount.
Otherwise,
you're
devs,
don't
know
what
they're
supposed
to
do.
You
can
give
them
tasks,
but
you
never.
A
You
never
know
when
you're
ready
to
ship
the
product
you
just
yeah-
oh
yeah,
we'll
just
keep
doing
this
and
this
and
this
and
the
product
goes
project,
goes
on
forever
and
you
never
ship
it
and
expectations
are
never
managed,
but
you
have
to
manage
those
expectations.
Definition
have
done
so
this
is
what
we
came
up
with
and
had
some
questions
about
number
one,
and
this
was
my
thought:
the
solution
should
require
a
PhD
push
here,
dummy
it
should
be
drop-dead
simple.
A
So
we
have
to
make
this
simple
for
them
and
we
have
to
make
sure
that
we
do
everything
we
can
in
the
user
experience
not
just
the
code,
because
no
one
cares
about
the
code.
If
the
app
breaks
nobody
says
you
know
no
one
talks
about
how
great
your
code
solution
was.
They
just
think
the
app
sucks
suddenly.
So,
let's
make
this
insanely
easy
to
use,
put
a
lot
of
Bozo
proofing
in
it,
etc
and
container
there's
very
little
time
for
training.
We
have
to
ship
this
thing.
A
You
know
it
has
to
be
live
by
Wednesday.
Maybe
Thursday
I
think
it
was
Wednesday,
but
it
has
to
be
live.
There's
there's
not
a
lot
of
time
for
training
I
had
to
ask:
is
there
an
API
so
that
you
know
these
these
surveys
that
you
know
Qualtrics
is
is
collecting?
Is
that
is
there
a
ways
for
us
to
get
access
to
that
data
right?
So
we
have
to
build
something
and
yeah
building
an
API
takes
time
and
building
an
API
that
works
right
and
is
secure
takes
time.
A
A
How
are
we
going
to
track
that
and
do
we
need
to
build
an
API
endpoint
for
that
and
originally
I
wasn't
sure
if
we
were
going
to
need
it,
but
we
actually
ended
up
needing
an
ability
to
track
the
marriage
of
those
two
in
two
different
places
and
we'll
get
into
it.
But
as
your
table,
storage
is
just
a
kicks
ass
and
then
how
do
we
scan
the
data
because
these
guys
are
wearing
gloves?
Remember:
they're
not
going
to
enter
these
these
characters
and
you'll
you'll
see
that
in
a
moment,
yikes
so
well
what
we?
A
How
are
we
going
to
handle
that?
What
about
Windows
like
when
people
drive
up?
How
do
you
safely
scan
their
information
yeah?
The
the
handheld
scanners
that
like
Starbucks
uses,
won't
go
through
tint,
so
they
have
to
roll
down
the
window
if
that
person's
infected,
that's
a
longer
exposure
time
for
both
the
EMT
and
the
patient.
So
we
have
to
think
about
that.
Actually,
the
the
team
brought
that
up,
I
didn't
even
know,
I
even
think
about
them.
They're,
like
oh,
hey,
by
the
way
this
works
through
tint,
so
that
was
very
nice.
A
It
made
us
safer,
I
had
no
idea,
never
thought
of
it.
So
there's
a
QR
code
that
you
get
from
the
survey
and
then
we
ended
up
asking.
How
do
we
mark
the
kits
because
the
kids
don't
have
any
identifiers
on
them?
That's
easily
scannable
we're
not
gonna
go
play
around
the
OCR,
that's
just
silly.
So
what
we
decided
to
do
was
use
barcodes
using
the
code,
39
format
and
those.
A
Now
these
days
you
can
get
a
code
39
font
for
effectively
free,
there's
nuances
to
code
39
as
we
found
out,
but
that
ended
up
working
out
really
well
and
the
cool
thing
was
we
had
a
QR
code
and
then,
by
using
code
39
the
I'll
get
into
it
later
that
actually
helped
in
the
user.
Experience
having
those
two
separate
formats
and
well,
the
partners
cooperate
well
qualtrics
work
with
us.
Will
the
test
team.
You
know
the
people
make
the
kids.
Will
they
work
for
us,
the
testing
lab?
Will
they
work
with
us?
A
A
A
So
we
simplified
all
this.
Those
are
a
lot
of
questions
to
ask.
How
do
we
simplify
this,
so
he
came
up
with
three
things:
one.
We
have
to
easily
scan
the
QR
code
and
kit
ID
and
we
have
to
sanity
check
the
data
under
no
circumstances
generally,
should
we
be
storing
bad
data,
the
patient
must
exist.
The
kit
must
be
valid.
Let's
make
sure
that's
the
case
come
up
with
a
kit
scanning
process,
so,
printing
the
originally
we
were
talking
about
printing
the
labels
in
real
time,
I'll
get
into
that.
A
A
You
know,
let's
let
IT
not
be
an
issue
as
best
we
can
and
so
what
we
did.
We
decided
we'll
just
pre
print,
all
the
kits,
all
the
all
the
kit
labels
and
that
worked
out
great
because
we
can
print
like
you
know
a
few
hundred
each
day
and
they're
just
ready
to
go.
You
just
scan
the
patient.
Take
the
label,
put
it
on
the
KITT
scan
the
kit
done
nice
and
easy.
You
don't
have
to
worry
about
running
out
of
ink.
A
You
don't
have
to
worry
about
miss
printed
barcodes
because
you
take
care
of
all
of
that
at
the
beginning
of
every
day
or
the
evening
before
the
day,
so
yeh
then
storing
the
patient,
ID
and
kit
ID
for
later
retrieval.
We
were
concerned
about
the
API
side,
as
I
was
saying
before,
but
it
turns
out.
Qualtrics
has
a
really
nice
API,
it's
it's
well
documented
I
mean
it's
like
you
couldn't
ask
for
something
better.
A
You
know
just
for
an
effort
like
this
and
we
ended
up
finding
out
that
we
could
upload
the
the
kit
ID
as
a
field
in
the
survey.
So
we
could
basically
put
to
the
survey
the
the
kit
ID
and
now
we
didn't
even
need
a
storage
system
which
was
awesome.
The
API
was
already
built
very
awesome
stuff,
so
no
back-end
datastore
thank
God
for
small
favors.
You
kind
of
see
when
Tracey
and
I
figured
out
how
we're
gonna
do
the
labels
he
picked
up.
A
So
so
here's
some
of
the
things
you
know
what,
while
we
were
talking
about
this
stuff,
this
ends
up
being
I'm,
trying
remember
with
the
perfect
candidate
for
a
mobile
app.
So
with
this
yeah,
the
the
mobile
device
already
has
the
ability,
with
its
built-in
cameras,
to
scan
a
barcode,
a
QR
code,
basically
any
sort
of
code
it
could
scan
it
yeah
pretty
easily.
A
Those
libraries
are
out
there.
If
you
use
the
Ameren,
we
ended
up
using
zebra
crossing
I'll,
get
into
that
in
a
bit.
The
device
itself
is
mobile.
It's
you
know
it
doesn't
work
white.
It
will
last
all
day
on
a
single
battery
charge.
All
of
these
things
are
good.
Now
we
we
have
to
use
that
scanning
because
take
a
look.
This
is
the
patient
ID
and
it
is
case
sensitive,
so
imagine
having
to
manually
enter
that
with
gloves
on
no
effin
way.
You
wouldn't
do
it
you'd
give
up.
A
So
we
solved
that
with
the
with
the
QR
code
and
the
the
barcode.
This
right
here
is
what
we
originally
were,
or
what
I
originally
sketched
up.
If
you
take
a
look,
I
had
a
print
button,
yuck
so
glad
that
went
away
so
just
breaking
down.
Okay,
what
happens
here
you
know
after
something
happens,
QR
code
is
on
clipboard.
A
So
a
funny
story
about
this.
Remember
when
I
said
people
had
to
be
on
board.
Well
there
there
was
some
pushback
about
having
I
thought
it
should
all
be
on
one
screen
and
that
you
should
basically
scan
the
patient
scan.
The
kit
confirm
the
data
save
it
done
and
that
this
should
all
be
on
one
screen
at
no
time
should
it
be
confusing
what
your
next
step
was.
There
was
pushback
from
the
Qualtrics
side.
A
They
wanted
me
to
launch
a
web
browser
after
scanning
it
in
and
I
pushed
back
pretty
hard
on
that
yeah,
hey
they're,
they're
well-intentioned,
because
that's
what
the
state
was
already
doing,
but
just
from
a
user
experience
standpoint
I
could
just
see
the
technician
trying
to
figure
this
out.
One
thing
goes
wrong:
they're
stuck
in
an
interface
that
doesn't
look
like
a
mobile
app.
Any
number
of
quote-unquote
tabs
could
open
just
managing
the
state
and
their
expectations
would
have
been
really
bad.
So
I'm
glad
Fisher's,
said:
look
you
know
we're.
A
We
do
it
your
way,
no
I'm
like
yay.
Thank
you
and
it's
been
working
out
right.
We've
had
no
issues
there.
There
was.
There
was
some
hiccups
on
day
one
that
weren't
because
of
the
app
in
another
hiccup.
That
also
was
not
because
of
the
app
which
is
funny
it
has
to
do
a
code.
39
I'll
explain
that
one
later,
but
we
ended
up
getting
a
really
great
app
out
of
this.
A
So
I
I
want
to
take
a
moment
to
because
I've
written
a
lot
of
mobile,
apps
and
I
tend
to
get
the
same
as
ask
these
like
three
primary
needs
to
figure
out.
How
long
is
it
going
to
take
from
for
this
app
to
be
built
and
how
effective
is
it
going
to
be
you
know
and
and
what
are
the,
what
are
the
issues
and
scope?
So
there's
really
three
things:
one
and
I
don't
like
reading
from
slides,
but
whatever,
where
does
the
data
come
from
so
yeah?
A
Usually
this
is
an
API
or
the
user,
and
if
an
API
doesn't
exist,
it
can
take
a
long
time
to
build
one
so
yeah.
That
was
what
I
had
to
ask
fishers.
Where
does
this
data
come
from?
Can
we
get
it
easily
if
we
can
get
it
easily?
What
data
can
we
yet,
then,
once
we
have
the
data,
where
does
it
go
so
you
know
or
if
we
create
data?
Where
does
it
go?
You
know
when
we
manipulate
data,
where
can
we
send
it?
Do
we
store
it
locally?
A
Do
we
need
to
store
it
persistently,
which
in
this
case
we
do?
We
have
to
persist
it
after
we
married
the
patient
and
the
kit.
Well,
that's
another
API
so
same
issue.
Do
we
need
it
to
build
an
API
and-
and
thankfully
Qualtrics
had
a
really
good
solution
there
and
then
how
does
the
user
interact
with
the
data?
So
where
does
it
come
from?
Where
does
it
go?
That's
all
great!
A
A
It
was
the
only
way
I
could
leverage.
Most
of
my
knowledge
to
build
an
app
quickly
and
handling
tasks,
and
just
asynchronous
operations
in
c-sharp
is
just
so
much
easier
than
Objective,
C
or
Java.
So
at
least
to
me
it
was
so
that's
that's
how
I
got
really
into
xamarin
and
then
over
the
years
xamarin
forums
came
out,
so
I
had
xamarin
forums
back
when
you
had
to
pay
for
it
too,
when
you
didn't
so
before,
Microsoft
purchased
it
so
a
long
long
history
in
xamarin,
but
this
was
a
perfect
fit
for
xamarin
forms.
A
We
needed
iOS,
Android
and
Windows.
They
were
only
using
iOS
in
the
city,
but
I'm
thinking
hey.
If
other
municipalities
want
to
use
it,
they
might
have
Android
or
you
know,
be
it
phones
or
tablets,
they
might
have
Windows
devices,
be
it
tablets
or
laptops,
not
that
I'm.
A
fan
of
laptops
for
this
sort
of
product,
but
still
xamarin,
makes
that
really
easy
anyway.
A
So
whatever
of
course
I
only
had
a
day
or
so
to
build
this
so
using
a
language
and
platform
I
know
is
paramount
and
I
needed
to
quickly
build
the
API
access
and
the
scanning
features
and
both
of
which
I
was
I
knew
a
lot
about.
On
the
xamarin
side,
the
funny
thing
was
on
Sunday,
so
this
is
Saturday.
Remember
that
I
got
the
the
mail.
The
email
I
received
or
I
was
planning
on
working
on
this.
A
This
mentoring
app
because
I'm
part
of
the
youth
mentoring
initiative
here
in
Indy
and
I've
been
working
on
their
app
and
I
kind
of
in
dragging
my
feet
on
it.
It's
a
pro
bono
project
but
had
scanning
in
it
for
scanning
in
the
safe
ID,
for
the
mentors
to
check
in
at
the
school.
So
I
end
up
working
on
this,
particularly
at
the
the
Kovan
scanning
patients
can
again
on
Sunday
instead,
so
I
continued
to
track
my
heels
on
my
my.
A
A
So
a
bit
about
the
tech,
a
lot
of
stuff
got
used
here,
xamarin
forums,
obviously
for
the
shared
UI
gosh
every
every
time.
I
look
at
how
much
code
is
shared.
It's
just
it's
just
phenomenal,
so
great
job
to
the
same
room
team.
They
just
keep
hitting
it
out
of
the
park
and
the
fact
that
they
listen
to
the
community
and
add
features
based
on
that
and
just
keep
things
solid.
A
That's
just
phenomenal,
so
barcode
scanning,
like
I,
said
it
was
already
mostly
complete
and
that
other
app
I
use
zebra
crossing,
that's
not
Xing
or
Zeke
Singh
or
anything
it's
zebra
crossing.
You
can
even
download
that
from
the
Google
Play
Store.
If
you
want
to
check
out
zebra
crossing
just
scanning
out,
they
wrote,
but
free
library
been
using
it
for
years.
It's
very
good,
it's
incredibly
powerful!
A
A
It's
it's
really
cool
I'll
show
you
what
that
looks
like
in
a
bit
and
maybe,
if
there's
a
need,
I'll
eventually
use
poly,
which,
if
you
look
that
up
it's
it's
really
cool,
so
you
can
put
it
automatic
retries
and
you
can
even
work
this
in
with
like
a
kvetch
and
start
using
a
your
like
local
store,
Ridge
or
it
probably
a
local
caching
of
data.
But
we
didn't
need
to
go
crazy
on
this
reef.
It
worked
great
because
it
was
very
easy
to
understand
what
the
end
points
were
and
and
create
my
clients.
A
So
basically,
once
you've
created
the
interface,
you
can
just
new
up
a
client
that
implements
that
interface
and
it's
it's.
It's
fascinating,
you'll,
see
it
in
a
moment,
samer
and
essentials.
I
I,
don't
know
anyone
who
doesn't
use
this
unless
they
didn't
know
about
it.
But
xamarin
essentials
is
amazing.
It's
I
think
it's
included
yeah.
It's
include
by
default
and
all
new
xamarin
projects
yeah
xamarin
essentials
is
it
takes
care
of
so
many
things
for
you.
A
I've
got
a
xamarin
essentials
video.
So
if
you
go
the
indie
xamarin
playlist
or
if
you
just
look
back
through
some
of
our
previous
presentations,
where
I
presented
on
xamarin
essentials,
I
cover
that
in
great
detail
and
actually
I
think
James
montemagno
showed
up
and
he
was
answering
questions
which
was
awesome.
A
So
then,
of
course,
I
ended
up
using
Azure
table
storage,
because
I
found
out
that
we
needed
to
make
sure
people
didn't
scan
the
same
kit
twice.
So
what
was
happening
is
they
would
have
like
this
just
the
sheet
of
paper
with
all
the
I
don't
know
any
photo
of
it.
I
don't
know.
If
I
have
that,
oh
yeah,
you
can
kind
of
see
the
the
sheet
of
paper
here
with
all
the
labels.
A
A
So
we
added
that
feature
to
prevent
it
and,
as
your
table
storage
is
so
incredibly
powerful
when
it
comes
to
just
quickly
standing
up
indexed
storage.
You
know,
just
you
know
it's
it.
It's
great!
You
know
if
you
just
have
a
simple
key,
very
easy
and
then
I
used
SVG's
to
keep
things
nice
and
crisp
on
the
screen.
A
I
used
screen
fonts,
rather
than
the
default
fonts
screen
fonts
that
I
really
enjoy,
and
then
what
was
it
called
I
knew
I'm
blanking
on
the
name
but
open
sans.
That's
what
it
was
open
sans
great
thought,
very
easy
to
read
lots
of
variations
and
then
prefer
the
image
loading
I
used,
FF
image,
loading
set
of
the
built-in
stuff
and
xamarin,
and
then
M
fraktur
was
what
I
use
to
import
all
the
graphic
assets
import.
A
A
These
would
turn
green,
and
you
would
know
that
it
is
now
okay
to
finish
the
check-in
I'm,
not
sure
if
I
get
to
it
later,
but
we
ended
up
having
a
revisit
this
a
little
bit
just
a
little
bit
of
the
color
scheme,
but
it
and
it
worked
really
well.
You
know,
like
people
understood
how
to
use
it,
you
can
see
where
I
was
playing
with
the
the
codes
yeah,
so
I
added
the
ability
to
when
you're
scanning
the
patient
it'll
only
scan
QR
codes,
but
when
you're
scanning
a
kit
it'll
only
scan
code
39.
A
A
You
know
it's
a
simple
change
in
code
that
prevents
confusion
by
that
non-technical
person
using
the
app
I
think
if
you've
ever
used
an
app
even
as
a
software
engineer,
I
think
you
use
the
apps
and
you
just
expect
them
to
work,
and
you
know
you
should
have
that
I
feel
you
should
have
that
same
expectation
for
your
own
software,
so
yeah,
that's
that's
what
I
did
I
was
like.
If
I
was
using
this,
you
know
what
might
I
how
how
might
I
have
issues
you
know.
The
other
thing
is
like
what
you
know.
A
A
So
finally,
we
did
some
tweaks.
So
when
we
were
when
we
were
done,
we
ended
up
with
this.
You
can
kind
of
see
what
this
ended
up,
looking
like
so
I
added
bounce
animations,
so
these
bounce
in
so
when
you,
when
you
scan
these,
this
will
animate.
So
using
the
animation,
libraries
and
xamarin
forms
I
made
that
bounce.
It
was
very
cool
and
it
gives
you
something.
You
know
it's
not
monotonous.
A
Look
a
little
nice
nicer
added
manual
data
entry
and
then
additional
color
changes.
So
the
one
complaint
we
had
was
this
looks
disabled
I,
never
thought
about
it.
Till
I
started
using
the
app
later,
but
this
button
I
ended
up
changing
the
color
and
the
same
here
all
these
buttons
so
that
they
didn't
look
disabled.
A
So
if
you've
ever
used
test
flight,
there's
a
basically
a
24
hour
minimum
time
for
Apple
to
review
it,
so
you
submit
the
app
and
then
you
wait.
App
Center
would
have
gotten
us
around
that.
Yes
and
and
I
use
that
religiously
now,
but
at
the
time
this
is
what
I
did,
and
so
we
submitted
it,
and
then
it
got
rejected
that
sucked
and
it
wasn't
for
anything
terrible.
A
Why
was
it
rejected
the
complaint
Apple
had?
Was
this
app
supports
scanning?
You
have
to
send
us
QR
codes
to
scan
and
barcodes
now,
as
the
barcodes
whoo
I'm,
not
sure
they.
The
big
complaint
was
the
QR
code.
I'm,
like
oh
okay,
I
mean
I
can
sing
you
QR
codes,
and
you
know
you're
just
going
to
trust
that
not
doing
anything
malicious
with
once
they
sing
at
you,
but
okay
and
right
here
this
this
this
shiz
says,
should
have
used
App
Center
I
should
have
updated.
This
oh
well
anyway,.
A
So
the
funny
thing
is,
is
I
had
to
give
them
QR
codes,
but
you
can't
attach
a
document
in
test
flight,
so
I
ended
up
having
a
get
the
these
put
together
and
then
send
them
a
onedrive
link,
I
I'm,
guessing
that
that
worked
because
within
a
day
it
was
within
a
few
hours.
It
was
accepted
and
was
available
for
testing
so
Hugh.
A
A
We
had
to
whitelist
the
the
Qualtrics
API
and
there
was
there
was
something
else
we
have
to
now:
I
think
it
was
just
the
Qualtrics
API,
so
the
the
phone's,
let's
see
the
the
iPads
there
cellular
connection
worked,
so
they
worked
or
no.
The
phone's
worked
fine,
but
the
iPads
went
one
of
them
didn't
so
we
were
using
Wi-Fi
and
it
wouldn't
work
on
the
Wi-Fi
enabled
devices
that
were
connected
to
to
the
city's
network.
So
we
ended
up
having
to
do
like
an
emergency
call
to
the
to
the
NOC
to
get
things
whitelisted.
A
But
everything
worked
out
well
and
the
next
day
we
a
dress
rehearsal.
So
this
is
was
this
Monday
monday
might
be,
Tuesday
might
be
Tuesday.
Now
it
is
Tuesday,
so
we
got
things
looking
really
good
on
Monday
and
then
Tuesday
we
decided
to
do
our
dress,
rehearsal
and
Tracy
introduced
it
we're
explaining
it
to
everyone
and
we
even
had
a
patient
that
fell
asleep
during
the
testing,
but
you
know
you
know
we
were
able
to
resuscitate
him.
That's
probably,
who
knows
you
know,
there's
a
he
need
oxygen,
and
none
of
this
is
funny
anyway.
A
Dress
rehearsal,
went
really
well,
didn't
really
have
any
issues.
The
Qualtrics
people,
by
the
way,
we're
very
easy
to
work
with
they.
They
were
available
even
at
like
nine
o'clock
at
night
when
we
had
issues
so
thanks
to
them.
So
then
we
passed
all
that
and
yay
day
one
day
one
came
through.
We
were
super
excited
everything's
been
going
really
well,
you
can
see,
there's
the
there's,
the
the
app
right
there,
all
right,
yeah,
that's
the
that's
the
device,
yay
there's
all
the.
A
Labels
and
you
kind
of
see,
you
know
this-
is
what
those
kits
look
like,
so
they
don't
have
any
labels
on
them.
You
just
have
you
know
information
about
it.
You
can
kind
of
see
the
the
masks
they
have
to
be
used
by
the
guys.
You
know
they
they
were
telling
me
hey.
You
know
we
tested
this
and
it
works
really
well
through
these,
these
this
tinted
glass.
So
the
area
will
spend
less
time
right
here.
They're,
not
scanning
they're,
actually
just
spinning
it
in
someone's
nose.
A
You
can't
see
that
there's
all
the
gloves
they
have
to
use,
so
you
can
see
you
know
like
imagine.
If
we
had
to
set
up
the
laptop
here,
I
mean
you
got.
You
have
no
room
over
here.
Imagine
having
a
run
power
to
this
table
just
to
have
a
scanner
run,
maybe
it's
it
would
be
insane.
So
the
mobile
app
was
absolutely
the
right
approach
here.
A
We
did
have
a
couple
issues.
One
was
you
know
the
the
scanning.
The
kit
twice
I,
already
explained
how
we
got
around
that
one,
basically
using
table
storage,
so
we
still
didn't
really
need
an
API,
because
you
can
just
use
the
azure
client
to
store
the
the
mapping,
so
you
don't
scan
duplicates.
But
here's
the
fine
thing
remember
I
said
there
was
a
QR
code.
You
know
that
you
got
as
your,
so
you
would
get
a
QR
code
sent
to
you
after
you
filled
out
this
assessment.
Well,
the
problem
was.
A
They're
having
a
do
manual
data
entry,
so
they
had
to
set
up
a
computer
because
they
would
scan
some
patients
and
the
QR
code
couldn't
be
found
in
the
Qualtrics
system
or
the
patient.
Id
couldn't
be
found,
and
so
you
I
get
a
yeah.
Just
a
frantic
call
from
Tracy
what
the
heck
is
going
on.
What's
going
on,
what's
going
on
and
like
why
this
doesn't
make
any
sense
Tracy,
you
know
so
I
go
because
I
had
signed
up
for
the
Freak
Ovid
testing
and
I
got
a
confirmation.
A
Email
and
I
got
a
confirmation
text
message.
So
I
scanned
in
the
emails
QR
code
and
the
app
worked.
Fine
I'm
like
I,
don't
get
it
so
I'm
like
so
then
I
opened
up
the
link
that
was
sent
to
me
in
the
text
message
and
it
presents
a
QR
code
that
QR
code
can
the
patient
can
be
found
so
I,
yeah,
developer,
yay,
I
drop
into
debug
mode
and
I.
Take
a
look
at
the
QR
code.
That's
coming
back
from
each
of
them,
one
of
them's
missing
a
character.
A
So
it
wasn't
my
app
that
had
the
issue,
but
Qualtrics
had
to
fix
something.
Luckily
it
was.
It
was
a
quick
fix,
but
you
know
we
had
that
one
issue
during
the
day
and
then
a
couple
days
later,
I
had
the
manual
data
entry
feature
completed
just
in
case
that
happened,
but
then
they
never
really
had
to
use
it.
Oddly
enough,
so
whatever
that
tragedy
averted
the
the
other
issue
that
we
had.
A
Let
me
let
me
see
here:
oh
yeah,
I'll
get
to
them.
Oh
and
the
other
issue
that
we
had
is
right.
Around
mm
user
or
1200,
1200
patient,
the
barcode
stopped
working
and
I
get
another
frantic
call
from
Tracy
and
he's
like
hey.
You
know
we
can't
scan
barcodes
any
more
QR
codes
are
fine,
barcodes
won't
work.
What
do
you
mean
and
so
I
said?
A
Send
me
a
copy
of
the
you
know,
send
me
a
copy
of
the
sheet,
the
barcodes.
You
know
they're
having
issues
and
if
you
know
anything
about
code
39,
the
string
has
to
be
asterisk,
whatever
text
and
then
asterisk
well.
For
some
reason,
all
the
barcodes
after
1200
we're
missing
the
asterisks.
So
now
it's
not
a
valid
code.
39
code,
not
it
won't
scan
and
so
I
said:
hey
Tracy
aren't
asterisks
missing
he's
like
oh
crap,
so
all
you
had
to
do
was
reprint
the
labels
and
we
were
set
so
again,
not
the
app.
A
But
you
know
these
things
happen,
and
this
is
why
we
pre
print
the
labels.
So
imagine
that
you
know
if
it
was
a
bug
in
the
code
and
you
had
to
fix
it
to
do
you
know
the
printing,
but
no
and
this
you
just
reprint
the
labels
always
get
in
the
world
so
day
one
went
fantastic
and
we
we
learned
a
lot.
So,
let's
you
know
look
about
one
month
later,
we
did
have
a
day
where
connectivity
was
lost.
A
They
solved
that
by
switching
over
to
cellular,
but
in
the
future,
we'll
have
to
figure
that
out,
you
know
I,
it
would
turn
my
roof
of
the
app
crashed.
I
think
that
the
app
crashed,
because
even
even
though
I'm
usually
good
about
this
I
wasn't
checking
for
connectivity,
I
fixed
it,
but
it
didn't
matter
because
once
they
switched
them
over
to
cellular
everything
was
good.
A
Testing
was
paramount.
Have
we
not
tested
this
prior
to
launching
it
I
think
things
could
have
gone
badly,
but
I
think
we
tested
it
fairly
thoroughly
and
I
was
even
checking
with
our
fire
chief
today
and
he's
like
it's
been
going
great,
it's
been
going
like
gangbusters
and
we've
had
zero
issues
with
the
app
and
that's
what
I
think
every
app
developer
wants
to
hear.
There's
no
complaints,
people
like
using
it,
it
just
works.
Those
are
all
good
things.
A
We
resisted
the
urge
to
add
useless
new
features.
We
we
didn't
need
feature
creep.
The
app
does
a
great
job
doing
what
it's
supposed
to
do,
but
we
did
embrace
a
better
user
experience
so
by
thinking
about
our
users,
and
we
only
had
one
piece
of
feedback
to
make
it
better.
Like
I
said
you
know
the
the
the
greying
it
out,
yeah
I
think
that's
what
helped
make
this
a
success
which
yeah,
if
you
look
right
next
to
that
everything
quiet
is
sometimes
the
best
feedback.
I
think
that's
insanely.
A
True
I
I
had
to
fight
the
good
fight
in
the
name
of
UX
so
when
they
want
to
when
there
was
a
push
to
move
this
to
be
both
app
and
web-based
I
I
really
dug
in
on
that
one
so
glad
I
did
manual.
Entry
is
okay,
but
if
you're,
not
careful,
people
will
try
to
bypass
the
rules.
So
we
had
to
tighten
that
up
a
little
bit.
A
A
Just
it's
it's
great.
Even
though
we
should've
used
the
App
Center,
a
test
flight
is
really
good,
as
retable
storage
was
so
easy
to
set
up
when
we
needed
it
so
that
we
didn't
have
to
build
an
API
to
do
secure
storage
of
information,
and
there
was
no
PII
info
anyway,
but
you
know
the
libraries
they're
just
made
it
very
easy
for
us
to
do
this,
and
then
you
know,
App
Center,
of
course,
is
insanely
insanely
useful,
so
I'm
gonna
get
into
some
code.
Now
so
I'll
say
the
questions.
A
A
A
A
A
A
B
A
Oh,
it's
my
screen,
not
shared.
Oh
I'm.
Sorry,
look
at
the
option.
I'm
telling
you
that
all
this
stuff
is
happening
and
all
right
now
can
you
see
it
yep?
Okay,
you
know
what
I
did
I
probably
hit
this
instead
of
this
okay.
So
here
you
can
kind
of
see.
You
know
we
had
patient
QR
code,
validation,
errors,
very
low
declined
to
continue
when
the
kit
was
already
assigned.
So
it
looks
like
we
actually
had
some
duplicates
people
trying
to
do
some
duplicate
entries,
but
we
didn't
allow
them
to
do
it.
