• Architected the AWS EKS infrastructure underpinning a production RAG-based AI platform across 3 environments—delivering a fully managed AWS service stack, ChromaDB vector store, autoscaled Celery job processing, and a Helm/ArgoCD GitOps deployment pipeline from the ground up.
• Architected and led production Kubernetes migration from KOPS to EKS with zero downtime, implementing GitOps (ArgoCD), Helm-based deployments, IRSA-based IAM, and Karpenter autoscaling—reducing operational overhead and enabling self-service deployments across engineering teams.
• Led another post-acquisition migration of production from EC2/Docker Compose to EKS + ArgoCD with GitOps CI/CD with zero data loss, while cutting deploys from 40 minutes to 5 minutes
• Implemented Container Insights on EKS clusters to monitor resource utilization, enabling workload right-sizing and an estimated 10–20% reduction in EC2 costs.
• Embedded DevSecOps by automating Wazuh agent deployment across AMIs via Ansible + AWS Image Builder, reducing manual security configuration time by 80%.
