Hi, I’m Devesh Sangwan.

I build useful full-stack products with React, Next.js, Node.js, and TypeScript, backed by systems that behave under pressure.

Where I’m useful.

Product-minded engineering, typed from interface to infrastructure.

Turning rough workflows into React and Next.js interfaces that feel clear, fast, and considered.

Keeping client, API, and data contracts aligned with TypeScript, tRPC, and shared boundaries.

Shipping real-time data flows and mobile companions without losing sight of failure states.

Featured Projects

The two projects I would lead with: useful, typed, and built around real workflows.

A small preview of what I write about: practical frontend patterns, tradeoffs, and the parts that start to matter after the demo.

A few weeks ago, the React community was buzzing after the useEffect debacle at Cloudflare. If you’re…

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