About

Who I Am

I'm an IT support and systems professional based in Poulsbo, Washington. As an IT Support Analyst for the U.S. Army, I administer Active Directory, harden endpoints, and manage network access control across classified and unclassified DoD networks, using tools like ServiceNow, Cisco ISE, and Trellix/HBSS to keep systems secure and mission-ready.

Six years diagnosing and repairing detection and communications systems in the military, plus four years running enterprise help desk support for 50,000+ users at Rutgers, where I earned my degree in IT and Informatics with a cybersecurity focus. Military-grade systems experience, enterprise support, and formal security training. That's the technical foundation I bring to every environment I work in.
