- Designed and maintained CI/CD pipelines with Jenkins across SIT through UAT to PROD, resolving build and deployment failures including plugin errors, dependency conflicts, executor issues, artifact gaps, permission problems, packaging errors, Docker issues, code check‑in issues, and container build failures to ensure successful artifact generation and pipeline execution.
- Provisioned servers for deployments via RLM and executed releases with Harness, supporting monthly PROD deployments while resolving server-side deployment challenges, ensuring reliability and minimizing downtime.
- Onboarded new pipelines from initial setup to deployment, providing workflow guidance where server provisioning, access, and prerequisites were handled upfront. Ensured smooth decommissioning of pipelines when they were no longer required, maintaining clean environments and reducing overhead.
- Troubleshot Kubernetes/OpenShift issues beyond basic pod failures, addressing node resource exhaustion, persistent volume claims, image pull backoffs, and networking misconfigurations to maintain cluster stability.
- Led workflow migrations from Bitbucket to GitHub and Jenkins to in‑house tools, guiding teams through repository restructuring, pipeline re‑creation, and access management to ensure seamless adoption. Assisted users in transitioning workloads to Docker-based VM deployments and ECS, providing troubleshooting support for image builds, container networking, and deployment rollouts.
- Monitored server health and performance using Grafana, setting up dashboards for trends, resource utilization, and error patterns to proactively identify and address issues before impacting releases.
- Handled incident and task queries, providing root‑cause analysis, upgrade support, feature fix changes, and resolving user queries during release cycles.
