Design, build, and operate CI/CD pipelines for containerized workloads across dev/test/prod, and implement core Kubernetes platform capabilities (RBAC, networking, ingress, secrets, autoscaling, and upgrades). Package and deploy services with Helm/Kustomize using repeatable release strategies, automate environments with IaC, and embed DevSecOps controls and GitOps standards. Improve operability with strong observability and incident practices, partner with application teams to onboard and troubleshoot, harden the software supply chain and artifact flow, and document platform patterns and templates to scale adoption.
