03Beyond the code

A mechanical engineer who fell for the web.

I earned a B.Sc. in Mechanical Engineering from Alexandria University in 2018 — then taught myself to code and never looked back. That engineering instinct for breaking big systems into clean, tolerant parts is exactly how I approach frontend architecture today.
