At BackgammonGalaxy, I build and maintain a Flutter monorepo for a real-time multiplayer backgammon platform across iOS, iPadOS, Android, and Web. The platform has 100K+ games played daily, and I developed WebSocket multiplayer features alongside XMPP chat and presence.

I also delivered game-learning and analysis features, and built native home-screen widgets and iOS Live Activities bridged to Flutter. I integrated RevenueCat monetisation and automated builds and releases with Codemagic CI/CD.

Before BackgammonGalaxy, I led Flutter delivery at PartyPal, including AR experiences and real-time messaging. At Coretechies India Pvt. Ltd. and as a freelancer, I delivered Flutter apps, including a secure chat app with Signal Protocol encryption and offline support.
