What I'm looking for

I seek a role building impactful mobile apps with Flutter where I can drive architecture, performance optimizations, testability, and mentor engineers in a collaborative, product-focused team.

I am a Senior Flutter developer with extensive experience building scalable, high-performance cross-platform mobile applications using Flutter, Dart, and Firebase. I lead feature design and implementation, introduce architectural improvements like MVVM/Stacked and clean architecture, and ensure quality through unit/widget tests, code reviews, and publishing to app stores.

I have delivered production apps with advanced capabilities — real-time object detection, AI-powered chat, content moderation, analytics, ads integration, and offline caching — and I emphasize SOLID principles, performance optimization (isolates, ObjectBox, caching), and reusable, testable code.
