Achievements: - Reduced Infrastructure Costs by 78% by using Karpenter, Spot Instances and Savings Plans - Introduced infrastructure testing with Terratest - Migrated from Prometheus to VictoriaMetrics (cost efficiency, increased query speed, better for ingesting, storing and quering of large number of metrics) - Migrated from Grafana Loki to VictoriaLogs (cost efficiency, increased query speed, better query language, simpler deployment and configuration) - Migrated legacy infrastructure from AWS CloudFormation to Terraform + Terragrunt - Created multi-account AWS Account structure using AWS Organizations and Control Tower - introduced Atlantis for IaC GitOps - VPC security hardening - EKS security hardening Responsibilities: - Building CI/CD in Github Actions - Cost Optimization of Cloud - Regular Security Assessments, applying security best practices (Least privilege, Zero Trust) - Managing complex AWS infrastructure in 12 regions in Terraform, Terragrunt and Terratest - Configuration of Observability stack (VictoriaMetrics, VictoriaLogs, VictoriaTraces, Grafana, Vector) - Management of Kubernetes workloads in ArgoCD - Write infrastructure automation applications using Go, AWS SDK, k8s API Technologies: AWS, GCP, k8s, Terraform, Docker, Linux, ArgoCD, RDS, DynamoDB, Redis, Python, Go,

- Migrated from Prometheus to VictoriaMetrics which increased metric storage duration and sped up large queries - Created custom Grafana Dashboards in collaboration with developers, configured alert notifications via Slack and Telegram - Configured Gitlab CI/CD Runners, which sped up builds by 72% Technologies: Kubernetes, helm, Docker, Terraform, Linux, Ansible, Vault, ELK, Prometheus, VictoriaMetrics, Grafana, PostgreSQL, MongoDB, Redis, Git
