Penetration Tester Resume Preview
- Completed over 80 penetration tests across web applications, REST APIs, and internal networks, identifying 1,200+ vulnerabilities with 50 rated critical. Each engagement included detailed findings with proof-of-concept exploits and prioritized remediation guidance
- Discovered and responsibly disclosed 3 zero-day vulnerabilities in widely-used open-source libraries, receiving CVE assignments for all three. Coordinated with maintainers on patching timelines and verified the fixes before public disclosure
- Led a two-week red team engagement simulating advanced persistent threat tactics against a financial services client, achieving domain admin access within 48 hours through a chained attack path. The findings directly informed a $2M security infrastructure investment
- Wrote custom exploitation scripts in Python for automated testing of common misconfigurations in cloud environments and web applications. These tools reduced assessment time by about 40% and improved consistency across the team's engagements
- Created detailed remediation guides for the 10 most common vulnerability types and delivered knowledge transfer sessions to 15 development teams. Recurring instances of those vulnerability types dropped 65% in subsequent assessments
- Scoped penetration test engagements with clients, defining rules of engagement, target lists, testing windows, and deliverable formats. Managed client expectations throughout the engagement and adjusted scope when new attack surface was discovered
- Tested Active Directory environments for common attack paths including Kerberoasting, pass-the-hash, AS-REP roasting, and constrained delegation abuse. Found exploitable misconfigurations in 90% of the AD environments assessed
- Used Burp Suite Pro daily for web application testing, manually probing for SQL injection, authentication bypass, IDOR, and business logic flaws that automated scanners consistently miss. Manual testing accounted for about 60% of critical findings
- Wrote clear penetration test reports aimed at both technical and executive audiences, with risk ratings tied to business impact rather than just CVSS scores. Clients consistently rated the reports as the most actionable they had received
- Tested cloud infrastructure on AWS and Azure for IAM misconfigurations, overly permissive storage buckets, and exposed metadata endpoints. Built a cloud-specific testing checklist that the team adopted for all cloud-focused engagements
- Participated in a purple team exercise with the internal SOC, replaying real-world attack techniques while the blue team practiced detection and response. The exercise identified 7 detection gaps that were closed within the following month
