About Me

I'm a cybersecurity and IT infrastructure professional with over a decade of experience across municipal government, public education, and the U.S. Army. My work spans identity & access management, enterprise network security, virtualization, and endpoint management.

I've led technical teams in both civilian and military contexts — from managing city-wide network redesigns to supervising battalion communications in operational environments.

My approach: security and usability aren't opposites. Systems people understand and accept are more secure than systems they work around. I build with both in mind.

Philosophy

"A network locked down so tightly that users can't function defeats its own purpose. Security only matters in conjunction with user experience — treat usability as a security multiplier."

Case Studies

Network Redesign & Firewall Consolidation

Led a full network redesign for the City of Saratoga Springs, consolidating disparate firewall infrastructure into a unified Palo Alto NGFW architecture. Engineered GJIS-compliant network segmentation to isolate the Police Department on a separate logical network. Extended city fiber infrastructure to a new fire station, merging three previously siloed locations connected via legacy IPSec tunnels.

City-Wide MFA Rollout

Planned and executed multi-factor authentication integration across city government using Cisco Duo. Rather than mandating compliance, developed training materials explaining the security rationale to users — driving adoption through understanding rather than friction. Also integrated Apple Business Manager with Entra ID for streamlined MDM enrollment.
