// about
David Suwandi
Full-stack developer shipping mobile, web, and IoT projects end-to-end. I build Flutter apps, design Go & PostgreSQL backends, and wire them up to fast, reliable frontends.
From offline-first point-of-sale apps to real-time location sharing and ESP32-driven relay panels — I care about performance, maintainable code, and getting things to ship.
