Business Systems Developer

I build the software that runs real businesses — ERP modules, restaurant POS, delivery platforms, and production systems. Not prototypes. Systems people actually depend on.

about

Building software for real operations.

Started with desktop business applications in C#, then moved into web-based ERP, restaurant POS, and delivery platforms. Every system I've built runs in production — handling real orders, real money, real users.

Currently leading ERP development at Smart Account in Saudi Arabia, and running Request O'tlob — a delivery platform I founded that reached 2,800+ customers in 16 months.
