Learn from Dr. Kevin Maloy in 1hr how to write Healthcare Apps to connect to EHR systems, instead of spending weeks to become fluent in HL7 SMART on FHIR standard. Kevin is a practicing, board-certified Emergency Medicine physician who also codes. The meetup recording (with Q&A) is at https://youtu.be/alB-45nu0lo

1. Welcome to ServerlessToronto.org
1
“Empowering Developers
to be Healthcare Heroes”
with Dr. Kevin Maloy

2. Serverless Evolution (since FaaS started)
2
Serverless is New Agile & Mindset
#1 We started as Back-
end FaaS (Serverless)
Developers who enjoyed
“gluing” other people’s
APIs and Managed
Services)
#3 We're obsessed by
creating business value
(meaningful MVPs,
Products), focusing on
Outcomes – NOT
Outputs, and we mesh
well with Product
Managers
#2 We build bridges
between Serverless
Community (“Dev leg”),
and Front-end, Voice-First
& UX folks (“UX leg”)
#4 Achieve agility NOT
by “sprinting” faster
(like in Scrum), but
working smarter (by
using bigger building
blocks and less Ops)

3. Disconnect between IT & Business needs
3
How to help companies accelerate?
Technology is not the point => We are here to create Value
Adopting Serverless Mindset allowed us to shift the focus from “pimping
up our cars” (infrastructure/code), towards “driving” (the business) forward.
≠

4. Let’s bridge the Businesses & IT Gap by:
4
1. bringing more Business-focused
topics (like one today) to educate,
2. offering free Second Opinions on
Application/Data Architecture
modernization (to Businesses),
3. offering for-fee Consulting service
(regardless of how short they are),
4. connecting Cloud enthusiasts from
the Community with Employers
