Offensive Security Professional  ·  Penetration Testing & Red Team  ·  Rio de Janeiro, Brazil

Offensive security professional and operator of Brecha, a cybersecurity consultancy based in Rio de Janeiro. Around 9 years of hands on penetration testing across web, API, mobile and infrastructure.

• Penetration testing on web, API, mobile and infrastructure
• Red team and adversary emulation inside authorized scope
• Vulnerability research and exploitation, from analysis to proof of concept and weaponization
• Technical reporting with kill chain, CVSS scoring and remediation a team can act on

Every engagement runs under a signed contract and a formally authorized scope. I never test anything without documented authorization from the asset owner. Whatever is public in these repositories is here for research and defensive use.

Full spectrum security consultancy. On the offensive side we deliver penetration testing and red team. On the defensive side we handle SOC, monitoring, incident response, cloud security, DevSecOps and compliance.
