ABOUT

Building practical software that solves real business problems.

I'm a software engineer based in Cairo, focused on backend engineering, security, and system architecture. I care about the parts of a product users never see — the data model, the auth flow, the failure modes — because that's what keeps everything else standing.

Outside of client work, I write about backend architecture and contribute to a couple of open-source security tooling projects.

Where I add the most value

Three areas I focus on, rather than trying to be everything to everyone.

</>

Backend Engineering

Reliable services and APIs built with .NET and PostgreSQL — from first commit to production deploy.

Security

Auth flows, access control, and hardening reviews so the product stays safe as it scales.

⇄

System Architecture

Clean, documented systems and data models built to scale with the product, not against it.
