About Me

I'm a Computer Science student at Tanta University and a passionate Back-End .NET Developer. I focus on writing maintainable code, applying clean architecture, and securing applications with JWT.

I've built a complete Hospital Management System — a real-world project handling database design, server-side logic, authentication, and UI integration using ASP.NET Core MVC, Entity Framework Core, SQL Server, and JWT.

I continuously learn how to build systems that scale, perform well under load, and stay easy to maintain. I'm looking for a Junior Back-End Developer role where I can contribute to real projects, learn from experienced teammates, and grow into a reliable engineer.
