What I'm looking for

I'm looking to build reliable, scalable healthcare products where I can work across backend systems, mobile applications, device integrations, and product-focused engineering.

I've built healthcare products at PB Health and Fitterfly Health Tech, spanning scalable backend services, mobile applications, and medical-device integrations.

At PB Health, I contribute to Go-based microservices and a Backend-for-Frontend layer, built a React Native healthcare app, and developed native Android and iOS SDKs for real-time Libre glucose monitoring. I also led a two-engineer Samsung Health PWA integration and refactored legacy Ruby on Rails modules into reusable service classes.

At Fitterfly, I shipped a Flutter app with 100K+ installs, reduced production errors by 23%, cut API response times by 30%, and built integrations for Bluetooth glucometers and blood pressure monitors. I focus on clean architecture, reliable high-volume workflows, and product-driven engineering.
