What I'm looking for

A remote, full-stack role where I own features end to end, from architecture to launch, on AI products, commerce or platform work. I do best in small, product-minded teams that ship often and give engineers real ownership.

I'm a full-stack engineer with six years of experience shipping production software, and the founder of ByteShift, an independent engineering consultancy. I own projects end to end, from architecture to launch, working mainly in TypeScript, React, Next.js, Node.js, React Native and AWS.

At ByteShift, I led a ground-up refactor of Sateek Insights' AI chat platform for a US life-sciences company. It turned a basic chat window into a Perplexity-grade research tool with streaming answers, live source citations and charts generated from backend data. For The House Of Ascent, a New Jersey fragrance brand, I built a custom Square storefront with a blend builder, gift cards, bulk gifting and paid in-store bookings.

I also designed, built and launched Aghosham, a hyperlocal marketplace with a web app, iOS and Android apps, and a shared API. In its first 100 days it reached 100k+ visitors and 1M+ product views, and generated 1,000+ customer enquiries for vendors.

Before that, I was Frontend Tech Lead at Repute Networks. I helped scale their HR SaaS from one pilot client to six enterprise HR providers serving 45,000+ employer organisations. I also architected a widget SDK on Module Federation and halved page load times. Earlier, at BYJU'S, I led a product redesign that lifted engagement 26%, and built 200+ interactive Three.js/WebGL learning applets used by over 1M students a day.

I'm most interested in AI products, commerce and platform work, where I can own architecture and delivery.
