· Monitor application health, logs, integrations, and performance using Splunk, Grafana, AppDynamics, and Prometheus; provide actionable service metrics and trend reporting.
· Manage deployment validation, configuration, troubleshooting, smoke testing, and rollback planning across Kubernetes, OpenShift, and other container platforms.

· Working knowledge of SQL and NoSQL databases, Kafka, and production troubleshooting across integrated application environments.
· Experience using observability platforms such as Splunk, Grafana, AppDynamics, and Prometheus, together with Python, PowerShell, or similar.

· Experience leading onshore and offshore production-support teams and mentoring support engineers.
