About

I started coding because I wanted to build things that actually work — not demos, not prototypes, but production systems people depend on. That instinct led me through startups, open-source, and enterprise: from cofounding a fintech platform for UAE businesses to engineering insurance systems at AGT Software Partners.

What drives me is the space between engineering and product. I care about clean architecture, but I care more about whether the thing ships and solves a real problem. When I'm not writing code, I'm probably reading about distributed systems or contributing to open-source projects I believe in.
