About me

Building mobile experiences that ship.

I'm a Mobile Application Developer at Sparktech Agency in Dhaka, with 2.5+ years building production-ready cross-platform apps for iOS and Android — from social and dating apps to business tools, shipped end-to-end and live in the App Store and Google Play Store.

Skilled in Clean Architecture, Riverpod / GetX / Bloc, REST APIs, Firebase, Socket.IO, WebRTC, and payment gateways including Stripe, RevenueCat and Amar Pay. Open to new full-time, remote, or on-site opportunities.
