Highlights

Cut AWS spend 45% through FinOps analysis, rightsizing, cleanup of idle resources, and replacing Cluster Autoscaler with Karpenter
Reduced MTTR with an observability stack on Prometheus, Loki, Grafana, Jaeger, and Kiali, plus synthetic monitoring, an on-call rotation in Grafana OnCall, and a runbook on every alert. Cut alert volume 60% by rebuilding thresholds from past incidents, and moved Loki's storage to S3 for cheaper log retention
Built a self-service GitOps deployment platform on ArgoCD, Helm, and GitHub Actions that deploys 20+ customer apps in 3 minutes instead of 15, with automatic rollback
Led development of a live quiz platform on Kubernetes and built its Go and Python backends for live games, accounts, payments, and analytics. Load-tested it with k6 to 30,000 concurrent players and halved its AWS cost at that scale by compressing game state
Wrote modular Terraform and CloudFormation that stand up EKS clusters in 3 AWS regions in under 15 minutes, and migrated workloads between AWS accounts without downtime

Maintained multi-tenant Kubernetes clusters with Istio mTLS and automated backups of cluster objects and EBS/EFS volumes. Fixed recurring ArgoCD reconciliation and pod-eviction failures, and right-sized HA PostgreSQL (Patroni) to use 35% fewer resources.
Built CI/CD pipelines for web, mobile, and serverless apps that test, build, and deploy in under 5 minutes, with pull request previews, production approval gates, and GDPR data-residency checks. Automated routine ops work with Python and Bash.
Moved from nginx-ingress to an API gateway and tuned load balancing, DNS, CDN, and caching to lower request latency.
Put internal tools behind Keycloak SSO with role-based access, set up a secrets vault, and managed AWS IAM, company workspace accounts, and certificates.
Designed and built an auto-scaling, multi-AZ BigBlueButton platform on AWS, with a custom AMI that cut server launch from 11 minutes to 3 and scale-in protection for live meetings.
