What I'm looking for

I am seeking a role that allows me to further develop my skills in cybersecurity while contributing to innovative security solutions in a collaborative environment.

I am an Information Security Analyst with extensive experience in penetration testing, vulnerability analysis, and the defensive aspects of networks and systems. My work primarily focuses on evaluating the security of networks, web applications, and corporate infrastructures through both public and private Bug Bounty programs. I have a strong command of tools such as Burp Suite, Nessus, Nmap, and Metasploit, and I employ techniques based on the OWASP Top 10 and Red Team methodologies.

Currently, I work as a Bug Hunter and Pentester at IPV7, where I identify and exploit vulnerabilities in web applications and systems. My role involves developing clear technical reports with Proofs of Concept (PoCs) and collaborating with development teams to address security issues swiftly. Additionally, I serve as a Higher Education Instructor at SENAI/DF, teaching courses on Network Defense and Cybersecurity, where I emphasize practical training and real-world applications.
