Hello, I'm Bidyut.

Software Engineer/Designer

I spent the last 3+ years building products in startups, shipping features across the stack and solving real customer problems.

These days, I'm building Opensource UI , a free React & Next.js component library where every component is designed, built, and maintained by me.
