I'm Harsh Yadav. I design and build things for the web, full-stack, from start to ship. Currently building legal AI tools at Hammurabi. Before that, I was freelancing and shipping fast on Upwork.

Based in Pune, India. Open for freelance/contract work.

I care about the things most people skip. The edge cases, the impossible deadlines, the parts of a codebase nobody wants to touch. I'm currently shipping my way through building things that matter.

TESTIMONIALS

Harsh doesn't need to be told what to do. He sees the problem, thinks it through, and ships it. We never had to micromanage him once.

Seymen OzcelikCo-founder, Hammurabi AI

He picked up our entire frontend alone and ran with it. Deadlines were always met, communication was always clear. Exactly the kind of person you want on your team.

Murat Can KorkmazCo-founder, Hammurabi AI

Gave him the brief, got back a finished product. No back and forth, no missed deadlines. Just solid work delivered on time.

PrabalOwner, Qognition Agency

Harsh handled both the design and the code. He brought ideas to the table without being asked and the final product was better because of it.

Carl DimikFounder, Kleenestar

Really easy to work with. He gets context fast, doesn't block you with questions, and always delivers what he says he will. Good teammate.
