About me

I am an Information Technology student with a primary focus on offensive security. My interests and expertise include penetration testing, binary exploitation (pwn), and reverse engineering.

In addition to offensive security, I also have experience in defensive security and detection engineering, allowing me to understand attacks from both attacker and defender perspectives. I am familiar with Wazuh SIEM, log analysis, rule creation, and threat detection, which helps me design more realistic and effective security detections.
