Blumenau, BR
open to relocation · North America & Europe
CEH v12
Breaking things on purpose, then explaining exactly how to fix them. 8 years in cybersecurity,
the last several spent entirely on offensive security — finding the way in before someone
with worse intentions does.

❯ cat about.md
Penetration tester who runs a high cadence of engagements across web, API, mobile, and
internal-network targets — scoping, exploiting, and writing remediation guidance a
development team can actually act on.
Comfortable across the full modern offensive toolchain and testing methodologies
(SAST, SCA, DAST) aligned to OWASP, NIST, and ISO 27001. Automates the repetitive parts
so more time goes toward the interesting parts.
