About Me
The Engineer
Behind The Code.

I'm Ahmad Al-Zein, a Senior Software Engineer with 6 years of experience in fintech and eCommerce — spanning payment processing, compliance systems, investment platforms, and high-volume B2B commerce.

I've built and shipped systems across the UAE, Saudi Arabia, and beyond — handling millions in transactions with the security and reliability that fintech demands. I care deeply about architecture, code quality, and the long-term maintainability of what I ship.

B.Sc. Informatics Engineering, specialising in AI — Arab International University, 2022.
