About Me

I am a passionate Computer Engineering Student at Mansoura University (Class of 2026), based in El Mansoura, Egypt.

My journey in tech is defined by a strong, practical focus on designing and building robust back-end web applications using PHP (OOP) and the Laravel framework.

I possess a deep understanding of RESTful APIs, MySQL, and Architecture patterns like MVC and Service Layers. I'm eager to leverage these technical skills in a challenging team environment, solving complex problems through clean, optimized code.
