What I'm looking for

I'm looking to build secure, reliable cloud platforms where I can improve developer velocity through Kubernetes, GitOps, infrastructure automation, observability, and practical security guardrails.

I've built and operated secure cloud platforms for Verizon, QinetiQ US, and consulting clients, spanning AWS, Azure, GCP, Kubernetes, GitOps, and Terraform. At Verizon, I supported 100+ microservices on EKS and reduced deployment errors by 45%.

I architected a FinTech EKS platform that cut deployment lead time from two hours to 12 minutes, and built Backstage golden paths that reduced new-service setup from three days to 30 minutes. My work combines ArgoCD, Terraform, Cilium, Istio, Vault, observability, and policy-as-code to give developers safe self-service capabilities.

I've led incident response, chaos testing, compliance automation, and engineering training. I bring the mission-readiness discipline of U.S. Army service to production reliability, security guardrails, and practical developer enablement.
