Container Platform Administration: Administer and operate Red Hat OpenShift Service on AWS (ROSA) clusters, overseeing cluster upgrades, node scaling, Operator management, Helm charts, and containerized workload orchestration.

CI/CD & GitOps Engineering: Design and maintain automated CI/CD pipelines (GitLab CI, Azure DevOps) and GitOps workflows (ArgoCD) for declarative application and infrastructure delivery.

Security & Compliance: Implement security controls, centralized secrets management (AWS Secrets Manager), least-privilege RBAC, NetworkPolicies, container security scanning, and automated guardrails (CloudTrail, GuardDuty, Security Hub).

Cost & Observability Optimization: Implement AWS cost optimization strategies (Reserved Instances, Savings Plans, rightsizing) while configuring CloudWatch observability, logging, and monitoring metrics for critical platform services.

Documentation & Support: Produce and update operational runbooks, architectural decision records (ADRs), and technical deployment specifications.
