01. About Me

I am a security practitioner dedicated to hardening systems and understanding attacker methodologies. My journey began with simple script kiddie curiosity and evolved into a professional passion for Ethical Hacking and Network Defense.

Currently, I focus on web application security, conducting vulnerability assessments, and automating threat detection. I believe in responsible disclosure and continuous learning in this rapidly evolving landscape.

When I'm not auditing code or analyzing pcap files, I'm participating in CTFs (Capture The Flags) or contributing to open-source security tools.
