§ 04 — About

An engineer
who ships the
whole thing.

I like owning a product from the protocol up — game servers holding real-time state for thousands of entities, token-metered AI pipelines, auth hardened with modern crypto, and the dashboards and landing pages on top of all of it.

Beyond the three flagship projects, I maintain 32 open-source projects spanning C, C#, Python, Dart, TypeScript, React, and C++ — CLI tools, TUI frameworks, HTTP servers, security utilities, AI pipelines, and more. I move fast without skipping the boring-but-important parts — tests, CI, encryption at rest, rate limits, and clean UX.

“I'm just as happy debugging a packet cipher as I am tuning a CSS grid.”

I build bilingual (English / Arabic, RTL) interfaces, and I'm open to full-stack, backend, AI-platform, and systems roles — remote or contract.

§ 05 — Contact

Available for full-stack, backend, AI-platform, and systems roles — remote or contract. The fastest way to reach me is WhatsApp; I usually reply the same day.
