About

A full-stack engineer with a designer’s eye.

I’m Shahin — a software engineer with 5 years shipping production software for high-traffic platforms. My happy place is the seam where an elegant interface meets a fast, well-architected backend.

Today I lead engineering at Cartup Ltd. Before that, at TechnoNext and Morpheus Soft, I built front-end teams, designed micro-service boundaries, and wired AI into real products — always optimizing for performance, accessibility, and developer joy.

Testimonials

Kind words from people who know me at work.

Shahin is one of the few engineers who can move fluidly between a Figma file and a production .NET service — and make both better in the process. He shipped our checkout rewrite a full sprint early.

I’ve worked with a lot of contractors. Shahin is in the top one percent for ownership. He treated our codebase like his own — refactored quietly, wrote tests, left it cleaner than he found it.

Preet S.

Corsica Health

The AI search integration Shahin built for our marketplace doubled the click-through on product discovery. Calm, methodical, and the docs were better than ours.
