Who I Am
I am an IT support and systems professional based in Poulsbo, Washington. As an IT Support Analyst for the NAVSEA Warfare Centers (NSWC/NUWC), I administer Active Directory, maintain endpoint security and compliance, and manage network access control across classified and unclassified DoW networks, using ServiceNow, Cisco ISE, and Trellix/HBSS to keep systems secure and mission-ready.
My background includes six years maintaining detection and communications systems in the U.S. Army and four years providing enterprise help desk support to more than 50,000 users at Rutgers University. I continue to build on that experience through a home lab dedicated to routing and switching, Windows Server administration, Splunk, and ACAS vulnerability scanning, and through scripting that automates routine IT tasks.
