What I'm looking for

I seek a senior-level cybersecurity/systems engineering role at a mission-driven organization where I can lead secure architectures, improve compliance, and mentor cross-functional teams.

I am a systems engineer and cybersecurity specialist with over 12 years of experience securing federal and private-sector environments. I design, research, and implement solutions aligned with DoD cybersecurity standards such as DISA STIGs and IAVMs.

I have deployed enterprise security stacks—Nessus/Tenable, Cylance, Microsoft Defender, Splunk SIEM, and FireEye—and led implementations that achieved full NIST 800-53/FISMA compliance with zero critical findings.

My background includes hands-on systems integration, large-scale patch and endpoint management using SCCM/Intune, VMware infrastructure architecture, and privileged access management. I have driven measurable improvements such as reducing vulnerability remediation time by 72% and decreasing security incidents by over 60%.

I collaborate closely with government leads, cross-functional teams, and vendors to deliver secure, cost-effective solutions while optimizing processes and maintaining regulatory compliance (PCI DSS, ISO 27001, SOX). I am pursuing CISSP and Azure Security (AZ-500) to expand my capabilities further.
