About

I close the gap between design and engineering.

With 6 years of experience building interfaces at SaaS companies across India, the UK, and Spain — I know what it takes to ship React applications that actually hold up in production.

What sets me apart: I design in Figma and implement in code. That means no translation loss, no endless back-and-forth, and no "it looked different in the mockup" conversations.

I've built component libraries from scratch, led frontend architecture for full products, ensured WCAG 2.1 accessibility at scale, and mentored engineers along the way.

Currently based in Ghaziabad, India — open to remote opportunities globally.
