What I'm looking for

I’m looking for a Penetration Testing role where I can run authorized tests end-to-end, prioritize critical findings, write actionable remediation reports, and collaborate with engineering/ops to validate fixes—while continuously learning emerging cybersecurity threats.

I’m an experienced Penetration Tester with 5 years in identifying and fixing security vulnerabilities across networks, applications, and infrastructure. I use advanced tools and methodologies to find and prevent critical threats while staying committed to continuous learning.

In every engagement, I conduct authorized penetration tests and vulnerability assessments, prioritize findings by risk and impact, and deliver detailed technical reports with root causes and proof-of-concepts. I collaborate with engineering and operations teams to validate fixes through retesting and improve security posture using threat modeling, offensive security testing, and guidance aligned to compliance requirements.
