Résumé ↗

Software engineer in Cairo. I build the part you actually touch.

Scroll — the wind starts with my name

01 About

The front of the stack is the part I love: the click, the scroll, the half-second a page takes to feel right. Six years and four teams in, I lead the tech at Adawy Software, and everything I know I learned by building it, then building it again.

  • Grounded → flyingEvery idea I'm handed arrives grounded. My work is teaching it to fly.
  • Built twiceThe first version teaches me the problem. The second one is the answer.
  • Fast, and for everyoneSpeed and accessibility aren't a last pass. They're how I build from the first line.
