Background & Philosophy

Senior Flutter Engineering Grounded in Production

I design, architect, and ship high-performance cross-platform applications — taking full ownership of state boundaries, cloud backend contracts, CI/CD pipelines, and app store releases.

With over 6+ years of specialized experience, I build cross-platform products that deliver native 60 FPS performance without cutting corners on architectural integrity or testability.

My core engineering stack combines Flutter and Dart with scalable cloud backends powered by Node.js, Firebase, Supabase, and PostgreSQL. I emphasize Clean Architecture (BLoC, GetX, Riverpod), secure database Row-Level Security (RLS), real-time WebSockets, and resilient offline synchronization.

Currently serving as Senior Flutter Developer at Health Automated LLC (UK), and formerly with ROXO (UAE) and Alright Tech, I have led engineering teams of 6+ developers and shipped 8+ production apps to the Google Play Store and Apple App Store Connect.
