At IT22 B.V., I deployed a 4-node OKD cluster on on-premises KVM infrastructure and now administer a platform supporting more than 25 production microservices. I support application teams with CI/CD pipelines, Helm configuration, and GitOps workflows across development, staging, and production.
I designed Tekton pipelines for containerized Maven builds and manage Argo CD with an App-of-Apps pattern. By connecting Git webhooks to OpenShift Pipelines and Argo CD, I removed manual deployment steps; I also stabilized builds by addressing recurring file descriptor errors and integrated Trivy scans into CI/CD.
