Open to Opportunities

Thinking Like an Adversary,
Defending Like a Pro.

Offensive Security Specialist & Ethical Hacker focused on Penetration Testing, Red Team Operations, and Vulnerability Research. I break defenses to build them stronger, exposing critical flaws before they can be exploited.

About Me

Professional Profile

The Offensive Mindset

I am a relentless Ethical Hacker and Red Teamer who believes the best defense is a relentless offense. My passion lies in dissecting complex systems, bypassing perimeter defenses, and uncovering logic flaws that automated scanners miss.

From Web Application Penetration Testing to simulating advanced persistent threats (APTs), I leverage a deep understanding of attacker TTPs (Tactics, Techniques, and Procedures) to fortify organizations. I don't just find bugs; I demonstrate business risk through controlled exploitation.

Proficient in Kali Linux, Metasploit, and Burp Suite, I specialize in black-box testing and authorized adversary simulations. My goal is to expose the invisible attack surfaces in your infrastructure before a malicious actor does.

Exploiting service vulnerabilities & privilege escalation.

Web App Security
