🧑‍💻 About Me

I'm a Mobile Application Engineer specializing in Flutter & Dart, building production-grade applications engineered for real-world reliability at scale.

I work at the intersection of mobile engineering, real-time communication, and backend systems — the kind of work where a dropped WebSocket connection or a laggy re-render actually matters to a real user.
