Offensive Security Team Lead

I am an experienced offensive security consultant with 7 years of hands-on experience in advisory and customer facing roles. As a seasoned offensive security team lead, I excel in executing complex penetration tests and guiding a team to secure critical infrastructure and applications. My unique blend of technical literacy and deep understanding of adversary tradecraft is reinforced by a Bachelor’s in Counterterrorism, Security, and Intelligence.

I am passionate about taking an intelligence-led approach to testing, and enjoy working collaboratively with detection engineering, threat intelligence and incident response teams. I am deeply fascinated when simulating real threat scenarios, and enjoy working in a technical leadership role where I can make a meaningful difference to disrupt threat actors and protect customers.

With a strong foundation in malware execution chains, evasion techniques, and enterprise IT network design, I have the technical proficiency to anticipate and counter advanced threats. I also enjoy researching the cyber crime landscape, tracking initial access brokers, sim swappers, crypto drainers, espionage specialists, exploit developers, violence-as-a-service, doxxers and more for my own threat research publications.
