About

Engineer first, developer second.

I'm a full-stack developer from Cairo with 4+ years building enterprise web applications. I care deeply about code quality, architecture discipline, and shipping software that actually works.

My path is unconventional — I studied Materials Science Engineering before falling in love with software. That engineering mindset shapes how I approach code: measure twice, cut once, optimize later.

Currently building GRC platforms at OSSUS and exploring Arabic voice AI with my side project, Sawt.AI.

Available for freelance projects, full-time remote roles, and technical consulting.

Always learning voice AI, vector databases, and how to orchestrate LLMs in production.
