About Me
Securing Systems Through Strategy, Risk & Compliance
“Cybersecurity is not just about tools and controls. It is about protecting missions, people, and trust.”
I am a results-driven Cybersecurity Analyst and Information System Security Officer with 8+ years of experience in risk assessment, vulnerability management, cloud security, and regulatory compliance. I specialize in integrating DevSecOps practices into the RMF lifecycle, automating security control implementation within CI/CD pipelines, and navigating NIST, FedRAMP, DoW and DoD compliance. I excel at managing the ATO lifecycle, implementing Zero Trust Capabilities and Principles, driving POA&M remediation, and ensuring continuous authorization readiness across secure cloud environments.
My background includes supporting mission-focused systems, maintaining security documentation, conducting assessments, and helping organizations strengthen their security posture. As a U.S. Army Veteran and Cybersecurity Professional, I bring technical knowledge, leadership, and a compliance-first mindset to every project from the Department of Defense (DoD), Department of Navy (DoN), U.S Space Force (USSF), Department of Veterans Affairs (VA).
