About

I'm a Software Engineer who enjoys building smart and useful things with code — especially on the backend, where all the behind-the-scenes work happens.

I started programming back in 2016 while studying at Ain Shams University. After graduating in 2019, I explored digital marketing for a short time, but my love for coding pulled me back. I started freelancing as a frontend developer, then found my real passion in backend development.

To level up my skills, I joined the ITI .NET & Angular track while continuing to freelance and build projects. Along the way, I discovered how much I enjoy teaching and sharing what I know. I became an External Instructor at ITI, where I've trained over 200 students in backend development and software best practices.

Later, I joined the Digital Egypt Pioneers Initiative (DEPI), a program by the Ministry of Communications, as a Software Instructor. There, I've taught MERN Stack and .NET to over 250 students so far.

I love making complex things easy to understand, and I'm always excited to help others grow as developers.
