Message

At General Dynamics Information Technology, I conduct vulnerability assessments across Regional Cyber Center - Army National Guard Enterprise environments using ACAS and Tenable Nessus. I prioritize findings with CVE and CVSS scoring, then verify remediation against DISA STIG benchmarks and POA&M entries.

Previously, I managed IT operations at The Association for Packaging & Processing Technologies (PMMI), including patch and vulnerability remediation workflows, identity platforms, and VPN infrastructure. I hold active CompTIA CySA+ and DoD ACAS Operator certifications, and bring experience with STIG compliance, RMF, and classified DoD systems.
