About Me

My Journey

With over 4 years of experience in cybersecurity, I've dedicated my career to protecting organizations from digital threats. My journey began with a Computer Science degree, but my passion for cybersecurity led me to specialize in ethical hacking, penetration testing, and security architecture.

I believe in the philosophy of 'thinking like an attacker to defend like a guardian.' When I'm not securing networks, you'll find me researching the latest threats, participating in CTF competitions, or contributing to open-source security tools.
