I build Kubernetes platforms and GitOps delivery systems for distributed industrial operations.

At BA Glass, I design and operate the Kubernetes platform behind an industrial modernization initiative spanning 13 manufacturing sites. I built a reusable GitOps operating model with Argo CD, Kustomize, Helm, and Helmfile across production, central, management, and non-production environments.

I've reduced application deployment time from roughly two hours to under five minutes through CI/CD and promotion workflows. I also built centralized observability and platform services for storage, secrets, load balancing, TLS, backups, and container delivery.

Earlier, I developed Java and SQL functionality for Altice Labs' Netwin platform and automated deployments with Ansible and Jenkins. I also built Kotlin and Micronaut backend APIs, database migration tooling, and tests for the Throdle social platform.
