What I'm looking for

I seek a role where I can lead defensive cyber teams, perform advanced threat hunting and incident response, work within RMF/DoD environments, and continue professional growth in a mission-driven, collaborative organization.

I am a dynamic cybersecurity professional with five years of hands-on experience in threat detection, vulnerability assessment, and incident response, built on 9.5 years of active-duty service in the United States Marine Corps.

I have led and mentored over 200 service members, achieving the rank of Staff Sergeant, and I have direct experience conducting threat hunting, hardening guidance, and implementing defensive controls using SIEM and EDR tools.

In operational and program roles I designed network architecture, reviewed requirements for split-based operations, and ensured RMF compliance for Marine Corps Cyber Protection Teams, and I served as a program manager implementing qualification assessment programs for defensive cyberspace analyst roles.

I hold industry certifications such as CompTIA Security+, GCIA, and GCED, possess an active TS/SCI clearance, and I am committed to continuous learning and improving cyber defense effectiveness.
