  • Cut NAT Gateway spend by 30% by localizing base images and adopting multi-stage Docker builds, which also shrunk image sizes and pod cold-start times across the fleet.
  • Set up split-horizon DNS on Route 53, using private hosted zones for VPC-internal service discovery and public zones for edge, keeping internal names off the public internet.
  • Configured AWS WAF with IP allowlisting to enforce VPN-only access to production, blocking all unauthorized external traffic and reducing the public attack surface.
  • Rebuilt the deployment stack from raw K8s manifests to Helm, publishing reusable helm-frontend and helm-backend chart libraries and migrating every service to a per-service values pattern.
  • Rolled out SigNoz for centralized logs, metrics, and APM across all production services, and defined SLOs, SLIs, and burn-rate alerts that replaced static thresholds with a real error-budget signal for engineering.
  • Built the AWS foundation in Terraform from day one (VPC, EKS, IAM, S3, ALB, WAF, Route 53) with reusable modules and PR-gated plan/apply, removing manual console changes.

  • Led the team that migrated critical government platform services from on-premise to GKE, end to end.
  • Upgraded 70+ MongoDB and PostgreSQL instances to Rocky Linux with zero downtime, clearing all end-of-life database versions.
  • Cut pod startup from 40s to 2s by moving 480+ artifacts from public to a local registry.
  • Migrated two large retail organizations from Odoo Cloud to GCP, owning the architecture and the deployment.
  • Automated GCP provisioning, IAM and configuration with Terraform, including label-based conditional IAM policies that enforce PCI DSS, ISO and GDPR compliance across the organization.
  • Rebuilt CD on ArgoCD and Istio for production canary deployments, using custom Helm charts in an App-of-Apps pattern.
  • Secured the edge with Cloudflare and Cloud Armor on GKE ingress, using Nginx Ingress and Cloud DNS sync for high availability.
  • Isolated tenants with Shared VPC and Kubernetes Network Policies, and removed plaintext secrets from code with SOPS and KMS.
  • Reduced GCP costs by 15% through instance standardization, and reclaimed 2TB of storage by tuning Prometheus.
  • Automated Solr replica scaling and collection management with a custom bot, cutting Solr costs by 30%.
