About

Flutter Engineer with 4.5+ years of experience building fast, scalable, production-grade mobile apps. I specialize in clean architecture, animations, state management, performance optimization, and building pixel-perfect UI for both Android & iOS. Strong areas: • Flutter & Dart / BLoC | MVVM / Clean Architecture • Custom animations, gesture systems, overlays, and WebView integrations • Native integrations (Android/iOS), platform channels, Firebase • Draggable sheets, complex UI/UX flows, scalable navigation • App performance: reducing jank, optimizing rebuilds, memory profiling • REST + WebSockets (with auto-retry logic) I enjoy taking end-to-end ownership — from architecture → feature development → testing → publishing → monitoring.
