At Karadeniz Teknik Üniversitesi – Bilgi İşlem Daire Başkanlığı, I worked on web application security, vulnerability scans, OpenVAS, and penetration testing during my cybersecurity internship.

As a CTF Team Member at AltaySec, I take part in national and international Capture the Flag competitions with the AltayCTF team. I contribute to technical analysis and solution development for web security, cryptography, reverse engineering, and digital forensics challenges.

My focus areas include web security, vulnerability assessment, penetration testing, OSINT, and CTFs. I’m also gaining experience in forensics, reverse engineering, and cryptography through competitions.

I’m a graduate of an Artificial Intelligence associate program and also work on projects in artificial intelligence, computer vision, and software development.
