About Me

A solution-oriented .NET Developer driven by a 'Why before What' mindset — prioritizing the understanding of business objectives to engineer the most effective technical solutions. With 2 years of experience in ASP.NET Core, I specialize in building secure, scalable systems using Clean Architecture and CQRS, ensuring every line of code serves a clear functional purpose.

Currently working at Smart Vision, developing end-to-end ASP.NET Core MVC applications for UAE government projects. Previously contributed to Codex Plans where I engineered enterprise multi-tenant systems spanning Hajj management, ERP, and clinic operations — designed to serve hundreds of companies with full data isolation per tenant.

My graduation project Raknah is a live IoT smart parking system integrating ESP32 hardware via MQTT, demonstrating the ability to bridge software with real physical systems. Graduated with Very Good from Port Said University — Information Technology and Systems.
