  • Monitoring and logging via AWS services (VPC Flow Logs, CloudWatch, CloudTrail).
  • Automation of network infrastructure with CI/CD and IaC.
  • Experience with container networking in ECS, EKS, and Kubernetes networking.
  • DNS and global routing strategies using Route 53 and latency-based routing.
  • Extensive experience deploying, managing, upgrading, and troubleshooting Amazon EKS clusters at scale.
  • Implement Kubernetes security controls including RBAC, Pod Security Standards, Secrets Management, Network Policies, and workload isolation.
  • Optimize Kubernetes platform reliability, observability, and performance using monitoring and logging solutions such as Prometheus, Grafana, CloudWatch, and OpenTelemetry.
  • Integrate Kubernetes platforms with AWS networking, IAM, security services, and CI/CD pipelines.
