Penetration testing and red-team lead at Knoa Pharma, who cut phishing-simulation click-through rates from 20% to 1%.

United States
Message

At Knoa Pharma, I plan and execute penetration tests and red-team engagements across network, web application, Active Directory, and social-engineering attack surfaces. I turn findings into remediation guidance and risk briefings for leadership.

I designed and led a phishing-simulation and security-awareness program that reduced employee click-through rates from 20% to 1% over 12 months. I also conduct threat hunting in CrowdStrike Falcon and Microsoft Sentinel, applying MITRE ATT&CK and OSINT intelligence.

At Purdue Pharma, I owned security reviews, vulnerability testing, and application hardening for TrackWise quality-management systems. I also developed Java web services integrating TrackWise with internal systems, embedding security controls at the integration layer.

My independent research includes an Active Directory attack-and-detection lab and Python utilities for reconnaissance and vulnerability triage. I hold the OSCP+ certification and have worked across offensive security, application security, infrastructure, and cybersecurity.
