What I'm looking for

I want to build and own cross-platform mobile products end-to-end, using clean architecture and dependable networking. I’m especially motivated by roles where I can drive releases, production support, and maintainable long-term code quality.

I’m a Flutter Mobile Developer with 6+ years of commercial experience building cross-platform iOS and Android applications. Most recently, I worked as the sole mobile developer on a B2C retail loyalty app, owning architecture, feature delivery, App Store / Google Play releases, and ongoing production support.

I focus on clean architecture, reliable network layers, and maintainable code. I’ve delivered end-to-end modules like receipt scanning, loyalty, services, and UGC (reviews & ratings with photo attachments), and built a production-grade networking layer with retry logic, request queueing, cancel-on-cleanup, and auth interception with automatic token refresh.
