• Optimize service performance, resource utilization, and reliability in Kubernetes environments.
• Collaborate closely with DevOps, cloud, and platform teams to improve system scalability and observability.
• Troubleshoot and resolve issues across Kafka pipelines, EKS workloads, and Terraform-managed infrastructure.
