The Story

Many Lives.
One Direction.

Born in New York. Raised on hard work and harder lessons. Spent years moving — South Carolina, Virginia, Florida, Illinois, Ohio, Texas, California, and Mexico — wearing every hat imaginable. Kitchens, door-to-door sales, every kind of grind there is.

Then came the international chapter. Cairo. Giza. Alexandria. Dubai. Pendik. Istanbul. Somewhere along the way, Egypt stopped being a destination and became home. I married Ahd here, became stepdad to Maria, and then Serene arrived in 2026. That changed the stakes.

At 45, most people are winding down. I'm still learning, still building, and still trying to make the next chapter bigger than the last.

The Work

Ideas Don't
Wait.

I don't sit on ideas. I build them — fast, lean, and real. Some ship, some become tools a team relies on every day, and the rest teach me something. These are the ones worth showing.

Live product

Prompt Duel

A voice-first AI battle game where words are the weapon. Speak your move in Arena duels, outwit Graves in a five-round Interrogation thriller, or win the room in a six-round Tribunal — ten AI opponents across two worlds, judged on tactics and creativity, not word count.

Built solo, end to end: game design, server-validated AI judging that resists prompt injection, guest-to-account progress, Stripe subscriptions, voice quotas, and tested, security-reviewed releases.

Agent Sandbox

Interoperability checks for autonomous AI agents. Point an agent at a neutral conformance partner over a public API and get a permanent, citable report plus a README badge. It scores what breaks when agents meet software they didn't grow up with: cursor discipline, duplicate suppression, and treating hostile payloads as data, not instructions.

Right Now

Alexandria.
Building.

Based in Alexandria, Egypt — on the Mediterranean. Running outbound sales for an AI robotics company by day. Building my own companies by night. Married to Ahd. Stepdad to Maria. Father to Serene.

Lately I've added bug-bounty research on HackerOne, using offensive security practice to become a sharper builder and tester.

The grind, the travel, the pivots — they all pointed here. The world is wide open and I intend to take full advantage of that.
