Who I Am

I'm a Computer Science Engineering graduate with an unwavering focus on cybersecurity. My core domains include Information Security, Network Security, Vulnerability Assessment & Penetration Testing, and Security Operations.

Currently training at Redteam Hacker Academy through the CICSA program — executing hands-on SOC operations, identifying OWASP Top 10 vulnerabilities, and applying real-world attack and defense methodologies daily.

My mission: think like an adversary, act like a defender, and help organizations build cyber-resilient systems from the ground up.
