Senior Flutter DeveloperGurugram, India

I build mobile products. Seven-plus years of it, mostly Flutter and Android — shipping apps to production, publishing packages on pub.dev, and owning what I build end to end.

About

I have spent most of my career on mobile — Android with Kotlin and Java first, then Flutter and Dart. I have shipped apps to the Play Store, published Flutter packages and plugins on pub.dev, and spent a fair amount of time on the parts nobody asks for until they break: security vulnerabilities, memory leaks and production releases.

These days I also build for the web with Next.js, TypeScript and Supabase. I like owning a piece of software end to end — the architecture, the code, the release, and whatever breaks afterwards.

Now

Just wrapped up at Junglee Games, where I owned Rummy Millionaire. Building TanpuraX at the moment — a Tanpura app with a native C++ audio engine — and working with Next.js and TypeScript, which is where this site came from.
