What I'm looking for

I seek roles where I can perform hands-on offensive assessments, expand red-team skills, mentor junior testers, and work in a security-first culture that supports continuous learning and real-world impact.

I am an independent cybersecurity researcher and junior penetration tester with hands-on experience performing over 40 simulated enterprise and web application penetration tests, delivering professional-grade reports and remediation guidance.

I specialize in uncovering and exploiting complex vulnerabilities including SSRF, XSS, SQL Injection, XXE, insecure deserialization, and Active Directory exploitation, and I automate workflows with custom Python and Bash tooling while leveraging Burp Suite, Nmap, BloodHound, and Impacket.

I am a Certified Bug Bounty Hunter, achieved Pro Hacker rank on Hack The Box, and am currently pursuing the Certified Penetration Testing Specialist (CPTS) credential to expand my red teaming and offensive security capabilities.
