Project: | GCP/GKE to AWS/EKS Cloud Migration
• Migrated a Java-based banking platform of 8+ microservices from GCP/GKE to AWS/EKS, ensuring zero data loss
and full feature parity.
• Resolved a production outage caused by memory exhaustion on t3.small worker nodes that prevented newly
autoscaled pods (HPA) from scheduling; implemented automated node scaling (Cluster Autoscaler) to dynamically
add capacity, restoring availability and preventing recurrence.
• Re-architected the database layer, migrating from GCP AlloyDB to AWS RDS PostgreSQL.
• Rebuilt CI/CD and GitOps pipelines using ArgoCD and Azure DevOps, switching the container registry from Google
Container Registry to Amazon ECR.
• Provisioned and managed infrastructure as code with Terraform — including VPC networking, security groups,
IRSA roles, and EKS managed node groups — across isolated non-production and production environments.
• Implemented end-to-end observability
