AppWork
Cloud-native maintenance SaaS cutting API latency 25 % and backing a US$ 13 M Series A.
The Story
From 2021–2024, as Lead Software Engineer, I transformed AppWork into a cloud-native, mobile-first maintenance operations hub for multifamily property managers. I refactored legacy Elixir/Phoenix services, integrated a React Native mobile app, and orchestrated end-to-end observability with Sentry and Oban—unlocking seamless workflows across RealPage, Yardi and MRI integrations to streamline operations at scale.

Every great solution begins with understanding the core challenges that need to be addressed.
Challenge 1
Refactoring monolithic Phoenix services and upgrading 40+ dependencies to support enterprise-scale workloads
Challenge 2
Achieving sub-second API latency under high concurrency without inflating infrastructure costs
Challenge 3
Ensuring robust reliability and comprehensive test coverage across a broad feature set, from work-order tracking to compliance reporting
How We Solved It
Strategic approaches and innovative solutions that transformed challenges into opportunities.
Solution 1
Upgraded core Elixir/Phoenix architecture and introduced property-based and end-to-end tests, boosting coverage from 62% to 88%
Solution 2
