About Me

Hello! I am Kerem Düz, a Computer Engineering student and cyber security enthusiast.

While hunting for security vulnerabilities among lines of code, in my free time I love exploring the world, experiencing different cultures, and collecting memories. Every new city gives me a different perspective.

I am developing myself in defense-oriented cyber security, network security, penetration testing, and malware analysis. My goal is to make the digital world a safer place.
