your Name

👋 I'm Mariem Hemdan

Frontend Developer & Data Engineer

I create web experiences that not only look amazing but also help your business work smarter, engage users, and achieve more.

I didn’t start my journey in tech by accident — it grew through curiosity, challenge, and hands-on practice. I’m a Computer Science and Artificial Intelligence student at Helwan University, passionate about web development and building real-world applications. I enjoy understanding systems from hardware fundamentals to user-facing interfaces. My background in Logic Design and Electronics strengthened my problem-solving skills and technical foundation. I’ve worked on projects ranging from responsive React applications to structured Java systems and UML-based designs.

I have hands-on experience with React, JavaScript, HTML5, and CSS3, with solid fundamentals in C, Python, and Java. Currently, I’m expanding my skills in Data Engineering and AI through the Digital Egypt Pioneers Initiative (DEPI).
