Hi, I'm Abdalrhman Yasser — a Computer Science student at Cairo University (Networking & Cybersecurity track) with a strong front-end development background. I build modern, responsive web and mobile interfaces using React, React Native, and TypeScript, and I bring a security-conscious approach to every project I deliver. I hold CCNA, CCNA Security, MCSA, and Ethical Hacking certifications, which means I don't just build interfaces — I build them with a "Secure by Design" mindset. I currently work as a Front-End Instructor and Head of the Front-End Committee at Minders Student Activity, and I've delivered full-stack projects (React, Node.js/Express, PostgreSQL) deployed on real production environments like Vercel and Railway.
