01About

Software Engineer @ Ente. Product-minded. Open-source.

I build and ship mobile apps end-to-end, mostly with Flutter + Dart - from the first product decision to the release that lands in someone’s hand.

I contribute to projects including Lichess Mobile and Traccar, and built Unfilter because I wanted to know what every app was built with.

Also: grew a tech community to 2k+, SIH national finalist, and Make-a-thon ’24 runner-up.
