What I'm looking for

I'm looking for hands-on security work where I can test web, cloud, Active Directory, and wireless environments, research vulnerabilities, build offensive tooling, and apply AI/ML security testing.

I've performed web application penetration testing and OSINT investigations for Fiverr clients across the US, UK, and Mexico, identifying SQLi, XSS, IDOR, SSRF, authentication bypass, and privilege-escalation vulnerabilities. I deliver technical reports with CVSS scoring and remediation guidance while maintaining a 5-star client rating.

I'm also conducting ongoing testing across web applications, Windows Active Directory, and wireless networks, including NTLM relay, Kerberos attacks, DACL abuse, and ADCS attack paths. I build security-focused tools and platforms such as BlackLabs, a hands-on web security learning platform, and a JWT Editor for Hackers, while applying Python, Flask, Docker, TensorFlow, and AI/ML security testing to practical systems.
