About

Great apps are crafted with
precision, passion and purpose

I'm a Senior Flutter Developer and Lead Mobile Engineer with 5+ years of experience building sleek, high-performance mobile apps for startups and fast-moving teams. My journey started with native Android and iOS development, but I quickly fell in love with Flutter's speed and flexibility for cross-platform app development.

I've led Flutter projects from scratch, refactored messy codebases into clean architecture, and shipped cross-platform apps that users actually enjoy. Clean architecture with Bloc/Riverpod, smooth animations, pixel-perfect UIs? That's my jam. I also know my way around Firebase, Supabase, REST APIs, and have experience with React Native when needed.

If you're looking for a Flutter developer who writes scalable code, thinks like a product owner, and genuinely cares about user experience — let's build something great.
