About
👋 Hey, I'm Haydar Abbassi aka hyzr I'm a 21-year-old Tunisian software developer and a software engineering student at the Higher Institute of Computer Science in Tunisia. My main focus is cybersecurity — especially vulnerability research and reverse engineering. I'm also a CTF player, mostly into pwn and rev, but I explore other categories too. I also do full-stack web development — and honestly, I’m just into building whatever’s buildable. If it runs code, I’ll probably mess with it. This site is both my portfolio and my blog, where I post writeups of CTF challenges I’ve played or authored.
