About Me

I'm Ali Alyami, known as D4rk_Kn1ght, a final-year Computer Science student at Najran University with a strong interest in cybersecurity and Capture The Flag competitions.

I spend much of my time solving CTF challenges across different categories, with a particular interest in Web Security, while also exploring Cryptography, Pwn, Reverse Engineering, and Digital Forensics.

Beyond solving challenges, I enjoy creating my own CTF challenges and turning security concepts and vulnerabilities into hands-on experiences.
