Three years. Four industries. One habit — ship it fast, ship it right.

I'm a full-stack developer working mainly in ASP.NET Core on the backend and React.js / Next.js on the front — with SQL Server, MySQL and PostgreSQL underneath. Over the last three years I've personally built 70+ production REST APIs, connected payment gateways across the GCC region, and shipped platforms used by state governments, banking partners, and large public events. I care about clean API design, fast queries, and code a team can actually maintain — not just code that works once.
