Chi sono
Senior Mobile Engineer with 7+ years shipping production iOS and Android apps.
I architect cross-platform systems in Flutter and React Native — enterprise apps serving thousands of daily users, where clean architecture, offline sync and release stability decide whether a product scales or gets rewritten.
I own the full lifecycle: architecture, modular design, performance, and App Store / Google Play releases.
Whether it's a new build or an existing codebase that needs work, tell me what you're building and I'll tell you honestly what it will take.
