About

I’m a Cloud Security Manager with 15+ years of experience securing federal and highly regulated cloud environments, specializing in FedRAMP, NIST 800-53, and Zero Trust architectures. I’ve led IAM and CyberArk programs supporting 10,000+ users, managed global security operations teams, and partnered closely with federal agencies, state governments, and executive leadership to strengthen security posture, improve audit readiness, and reduce operational risk. My background spans cloud security architecture, security engineering, SOC operations, compliance, and security product management, allowing me to bridge hands-on technical execution with program leadership and strategic decision-making. I hold an active U.S. Secret Clearance and am open to senior individual contributor or management roles focused on cloud security, federal cybersecurity, and regulated enterprise environments.
