01 — About

I don't wait for the right age to start.

I build now, learn fast, and let the work speak for itself.

Fastest solve
1:29

World record holder, at 13.

I set a world record for solving a customised Indian-Flag 3×3 Rubik's Cube in 1m 29s — recognised by the International Book of Records for innovation and patriotism. It's still the clearest proof of how I work: pick a hard problem, drill it until it's fast, ship the result.

AI integration

Prompt engineering and LLM-powered features shipped into real products.

Product design

Minimal, user-focused interfaces that stay fast and get out of the way.

Scalable systems built to handle growth without a rewrite.

04 — Testimonials

What people say.

Founders and teams I've shipped products with.

  • Rayyan took a rough idea and shipped a working product in weeks. Design, backend, deploy — all of it, on his own.

  • Fast replies, no hand-holding needed. He flagged problems before we hit them.

  • He asks the right questions up front, so the thing he builds is the thing you actually needed.

  • Store went from slow and clunky to fast. Orders followed within a month.

  • Scope stayed tight and the timeline held. Rare on a build this size.

  • Shipped past what we asked for, without inventing work nobody wanted.
