Hi, I'm Devesh Sangwan.
I'm a Software Engineer at Paisabazaar and a Computer Engineering graduate from Netaji Subhas University of Technology.
I like building efficient full-stack products with Node.js, TypeScript, React, and Next.js. The sweet spot for me is a useful interface backed by a system that behaves well under pressure.
Outside of programming, I travel, take photos, and spend an unreasonable amount of time in games.
This is what I'm currently up to:

Say hi.
I am always happy to talk about full-stack products, portfolio tooling, cricket score systems, or a good engineering rabbit hole.
