Business judgment.
My career has progressed from hands-on systems engineering to leading enterprise infrastructure and IT operations.
I have worked in consulting, education, financial technology, and nationwide logistics. Across those environments, the priorities have remained consistent: resilient systems, practical security, clear standards, capable teams, and disciplined spending.
Today I lead infrastructure, cybersecurity, systems administration, service desk operations, asset management, and technology governance at Xpress Global Systems.

Identity operations
Delegated administration
Implemented ManageEngine ADManager so Tier 1 technicians could safely complete defined administrative tasks.
Lifecycle automation
Onboarding & Offboarding APIs
Automated repeatable account workflows to improve speed, consistency, and auditability.
Modern management

Led the conversion of the workstation fleet to Entra join and centralized Intune management.
03
Risk, resilience & communications
Vulnerability management
Tenable + monthly operating rhythm
Established recurring server assessments and a documented mitigation procedure.
Compute platform

Replaced aging infrastructure while avoiding approximately $500,000 in renewal costs.
05
How I lead
The operating model
Make the system
stronger than the fix.
Translate technology into choices.
Executives need clear decisions about risk, cost, and opportunity. Technical teams need context and priorities.
Build security into operations.
Controls work when they are part of routine ownership, assessment, documentation, and response.
Use standards to create capacity.
Automation and defined processes reduce avoidable work and give teams room for higher-value problems.
Treat cost as an architecture concern.
Vendor terms, licensing, platform design, and lifecycle decisions belong in the same operating conversation.
