About me
I am a cybersecurity engineer with a foundation in computer science and hands-on experience in penetration testing, malware analysis, and threat detection. I am passionate about helping organizations secure their digital infrastructure by working on real problems, building on what I learn, and applying that knowledge to strengthen defenses.
As a cybersecurity researcher and active CTF player, I enjoy exploring real-world vulnerabilities, reversing malicious applications, and applying hands-on techniques to strengthen my skills. These challenges keep me grounded in how attackers think and how defenders should respond.
