Profile.

With over 4 years of experience from Gaza, Palestine, I work as a product-minded Full-Stack Product Engineer — taking ideas directly from clients, shaping them into clear user stories and UX/UI designs, then architecting and building the system end-to-end with React, Next.js, Nest.js, and Express.js.

I focus on owning the whole workflow: discovery, design, engineering, and delivery — so what gets built actually matches what the client needed, not just what was specified.
