The Human

I'm a Senior Software Engineer living in Amsterdam, originally from Egypt. I've spent 9+ years building systems that matter — elections platforms, judicial systems, government HR infrastructure, and enterprise tools used by thousands daily.

At KLM, I've evolved beyond pure engineering into a Product Engineer and BPA role — sitting between stakeholders and the codebase, translating business reality into clean technical solutions.

I take AI seriously as an engineering tool — not as a crutch, but as a force multiplier. I use GitHub Copilot and Claude daily to write better code, think through architecture, and move faster without cutting corners.

Outside work: I cycle around Amsterdam 🚲, train in kickboxing and jiu-jitsu, and explore product ideas in the Dutch market. Currently building in public.
