I'm a software engineer who cares about the small things — the spacing, the timing, and the way an app feels when it never drops a frame.
Over the last six years I've shipped mobile, desktop and full-stack products — most of it cross-platform work in Flutter, plus services in Node, Nest and Next. I like taking things end-to-end: defining architecture, sweating performance and accessibility, and leaving behind docs and tooling that make the next person faster.
I'm a Computer Science Engineering graduate from Saroj Mohan Institute of Technology (2016–2020), currently a Senior Software Engineer I at Degreed in Bangalore.
