16 Senior Site Reliability Engineer @ The Walt Disney Company
17 Managed observability platforms and Kubernetes infrastructure across 28 clusters spanning cruise ship and shoreside environments.
18 - Engineered high-availability LGTM stack (Loki, Grafana, Tempo, Mimir) across 28 Kubernetes clusters spanning cruise ship and shoreside environments using Helm charts and ArgoCD for GitOps, replacing redundant per-cluster configurations with a single standardized deployment
19 - Implemented Grafana Operator to standardize dashboards, alerts, and datasources across application teams, ensuring consistent observability across environments with intermittent connectivity
20 - Optimized LGTM configurations for cruise ship environments with limited connectivity, developing custom Grafana and Mimir alerts for early issue detection before on-shore teams could respond
21 - Led incident response for Kubernetes infrastructure, replacing manual remediation processes with Rundeck and ArgoCD automation to eliminate human error during outages
22 - Collaborated with application teams to embed Grafana Operator resources into their Helm charts, so monitoring, dashboards, and alerts deployed automatically alongside their applications
23 - Built multistage CI/CD pipeline for the LGTM stack, automating deployment, upgrading, and patching across development, staging, and production environments with integrated testing and approval gates for hands-off promotion to production
