Full Stack Developer · Mumbai, India

I don't prototype ideas — I ship them.

Real-time systems, multi-chain infrastructure, and production sites for paying clients.

Portrait of Kaif Khan

I build the systems businesses actually run on.

I'm a full stack developer who cares more about what happens under load than what a screenshot looks like. Most of my time goes into the parts users never see directly — order books staying in sync, price feeds not falling behind, wallets deriving the right keys on the right chain — because that's where products actually break.

I currently split my time between AdSaathi, an AI ad-management platform I'm building for Indian SME owners who don't have an in-house marketing team, and freelance client work — live sites for real businesses across real estate, government document services, and headless e-commerce.

I'm currently finishing my BCA at Tilak Maharashtra Vidyapeeth (2023 – 2026), and I learn almost everything by building the real thing rather than a tutorial version of it.

Shipped for real businesses, not just for a grade.

Three sites, three different industries, all live in production. This is the work I'd point a freelance client to before anything else.
