👋 Hi, I'm Abderrahim AKA ZeroDay
I’m a Computer Science enthusiast with a strong interest in cybersecurity, backend systems, and low-level programming. I enjoy understanding how things work under the hood, from networking simulations and operating systems to encryption algorithms and compilers.
Most of my projects revolve around:
🔐 Cybersecurity fundamentals and applied cryptography
🌐 Backend and full-stack web development (Next.js, Firebase, REST APIs)
☕ Java applications (CLI tools and GUI apps with Swing)
🐧 Linux-based development (Arch Linux user)
📡 Networking and system simulations
⚙️ Low-level programming (MIPS, systems concepts, transpilers)
📱 Cross-platform app development (Flutter)
I like building practical systems, experimenting with new technologies, and turning theoretical concepts into working implementations.
