What clients say.
Real feedback from founders and clients I've worked with.
”
Hassan has always worked to an extremely high standard throughout our extended projects working together. I would work with him again in a heartbeat. He has taken on much more than front-end dev work and is a real full-stack developer able to adapt to any given task. His attention to detail is his strength, and he can work autonomously — which is rare within the Upwork contractor world.

Upwork Review
”
Hassan and I have been doing engineering work quite closely on this project and it has been an absolute pleasure. He consistently goes above and beyond, genuinely taking great care in all the work he does. We're a small, new business, so he had to work on an unstructured, messy project being asked to deliver vague features — yet he broke through those barriers to not only deliver the initial goal but help provide structure to our team and codebase. I would 100% recommend Hassan to anyone!

Hassan is a true gem of a talent — the 1% that is hard to find. He has been critical in building so many of my applications as a 2x tech founder. I would hire him again in a heartbeat for my next project.

Hassan was instrumental in building a world-class product for consumer-first retail companies across the US. He goes from idea to completed product with very little direction.
