6 engineersdeveloped and promoted across three management roles
I came up through field engineering and moved through four Verizon roles over 13 years. That progression lets me connect engineering reality with executive decisions on reliability, cost, risk and delivery. I have led cloud migration, application modernization, monitoring, ITSM governance, security governance and FinOps under one operating roadmap.
What I lead
Five areas where I bring both operating depth and leadership accountability.
Infrastructure & cloud operations
Hybrid and multi-cloud operations across AWS and GCP, data centers and VMware. Modernized VMware across 1,000+ hosts with zero facility-level outages.
Reliability, observability & incident response
Grafana, Elasticsearch, alerting, anomaly detection, tracing, P1–P3 response and executive escalation leadership across enterprise workloads.
Service delivery & ITSM
ServiceNow ITSM, CMDB and ITOM Service Mapping; incident, problem, change and release management; disaster recovery and business continuity.
Vendor governance, budget & FinOps
Five vendors on a $5M portfolio, executive business reviews, contract risk scoring, multi-cloud FinOps and multi-million-dollar infrastructure budgets.
Technology modernization & team leadership
Cloud migration, microservices modernization, IaC, CI/CD, Scrum/Kanban and executive KPI dashboards—while developing leaders and promoting six engineers across three management roles.
Selected transformations
Three examples of modernization delivered without losing operational control.
110+ workloads to multi-region AWS
Scope. Mission-critical conversational AI and backend workloads handling millions of real-time transactions.
Leadership. Directed migration using Lambda, EC2, EKS, Bedrock, SQS and RDS, with blue-green deployments and active-active failover.
Result. 99.99% availability across production and staging while modernizing monolithic IVR systems toward microservices.
ServiceNow visibility across 100+ services
Scope. Enterprise ITSM, CMDB and ITOM Service Mapping from applications through infrastructure.
Leadership. Led the implementation and mapped 100+ business services for incident impact analysis and service governance.
Result. Created the service-mapping foundation later reinforced by Grafana/Elasticsearch monitoring and application tracing.
VMware modernization across 1,000+ hosts
Scope. Sacramento, Twinsburg and Tampa data-center environments.
Leadership. Modernized virtualization and consolidated the physical footprint while restructuring infrastructure investment.
Result. Completed the work with zero facility-level outages.
Governance & resilience
Operating discipline for environments where outages, audit gaps and uncontrolled change are expensive.
SOC Type I & Type II
Led annual SOC Type I and Type II audits from 2022–2025 across 110+ workloads and 2,000+ users, working directly with executive sponsors, compliance leaders and auditors.
Security, patching & vulnerability governance
Owned controls for access, patching, logging, backups, DR testing, change management and incident response. Team-managed vulnerability reviews and remediation across on-premises and cloud environments.
Disaster recovery & business continuity
Built DR and BCP practices from runbooks and regular testing, cutting recovery time 40% and bringing mission-critical services to 99.9% availability.
Executive visibility
Replaced spreadsheet reporting with executive dashboards for KPIs, SLA performance and operational risk, reducing monthly report preparation time 63%.
