  2. Kubernetes Migration & Workloads
    • Migrated applications from Docker Compose to Kubernetes.
    • Deployed workloads across multiple Kubernetes clusters in Google Kubernetes Engine (GKE) for high availability and scalability.
  3. Infrastructure & Automation
    • Implemented Infrastructure as Code (IaC) with Terraform.
    • Set up multi-account AWS cloud architecture and multi-hosted DNS zones for global accessibility.
  4. CI/CD & Deployment
    • Established a CI/CD pipeline using Google Cloud Build.
    • Implemented Spinnaker for continuous delivery across environments.
    • Stored and managed container images in Google Container Registry (GCR).
