Who I Am Experience What I Build

Who I Am

I'm a software engineer based in Cairo with a B.Sc. double major in Pure Mathematics and Computer Science from Ain Shams University. My academic specialization is computer graphics engines, B-spline curve and surface optimization, and sinc-based signal processing.

Day-to-day I architect and ship the full stack: I author Odoo 19 ERP modules, run their NixOS hosting, build the mobile and SaaS clients on top of them, and write the Go services and developer tooling that hold everything together. Most of what I build runs in production for real Egyptian and MENA businesses.

I work alone or with very small teams, communicate directly in Arabic and English, and prefer compile-time safety, small composable services, and aggressive deletion of unused abstractions over enterprise ceremony.
