Mex MrV
@mexmrv
Junior penetration tester on Intigriti and Bugcrowd, reporting exploitable web and API vulnerabilities.
AngolaWhat I'm looking for
On Intigriti and Bugcrowd, I research and report exploitable vulnerabilities in authorized bug bounty programs, including issues in web applications, APIs, and modern authentication mechanisms. I turn findings into clear, reproducible reports with severity ratings, proof of concept, and actionable remediation recommendations.
In my independent offensive security practice, I use CTF platforms to sharpen web exploitation, scripting, and CVE analysis. I also build and refine my own exploit scripts and reconnaissance workflows in Kali Linux.
I developed an independent academic management platform with a Node.js backend to digitize grade records and school administrative workflows, applying secure development practices from my offensive security training. I also developed an independent Python and ReportLab tool that generates client-ready penetration testing and vulnerability assessment reports, including severity-coded findings, CVSS scoring, and researcher signature validation.
My certifications include ISO/IEC 27001:2022 Information Security Associate, Certified Artificial Intelligence Security & Risk (CAISR), and Digital Forensics & Incident Investigation. I’m actively seeking junior offensive security positions, paid bug bounty projects, and freelance penetration testing work.
