Devops Engineer - Masters Intern @Pacific Northwest National Laboratory

Implemented a pg_dump backup pipeline on Kubernetes (CronJob + NFS PV/PVC, Secrets, retention) and automated its rollout via GitLabCI/CD, ensuring reproducible, recoverable datasets across teams.• Provisioned PostgreSQL via Helm on an HPC Kubernetes cluster (StatefulSet + PVCs, Secrets, NetworkPolicies) to back an LLM-drivenapplication, hardening connectivity and isolation so research services had a reliable transactional store without bleeding across namespaces.• Surfaced fleet metadata in Grafana for fast drift/CVE checks by emitting Ansible facts (OS distro, kernel release, host groups) through acustom Ansible callback to Graphite and wiring templated Grafana dashboards—giving ops an at-a-glance view of hosts that need patchingbefore scheduling research workloads.• Documented runbooks and Helm values (backup/restore steps, RBAC, storage notes, scheduling policies) so other engineers can reproducethe setup, and researchers understand constraints when deploying data or GPU workloads
