• Achieved a 90% reduction in bandwidth costs by implementing image caching through CDN, significantly lowering expenses while improving content delivery speed and performance.• Automated the end-to-end environment setup in AWS Cloud using Terraform, which included the configuration of VPC’s, subnets, route tables, gateways, EC2 instances, and EKS clusters.• Implemented HashiCorp Vault for Kubernetes secret management and automated the procurement and renewal of free Let's Encrypt certificates. This initiative resulted in substantial cost savings on certificates and streamlined operational processes, enhancing overall efficiency and security.• Developed a Kubernetes Operator to automate and manage ingress configurations, optimizing application load management and facilitating blue-green deployment strategies. This solution enhanced traffic routing, ensured zero-downtime deployments, and improved overall application availability and performance.• Achieved a 70% reduction in client DNS lookups by optimizing A/AAAA record configurations, resulting in a 50% decrease in DNS provider costs.

• Designed, deployed, and managed various infrastructure solutions on Microsoft Azure, including virtual machines, Kubernetes clusters, and storage accounts.• Migrated the monitoring stack to Kubernetes-based deployments, transitioning Prometheus, Grafana, Victoria Metrics, Zabbix and various open-source metric collectors to a more robust and scalable solution.• Designed and implemented several insightful Grafana and Kibana dashboards to enhance visibility and support for monitoring teams.• Migrated Elasticsearch clusters from VM-based to Kubernetes deployments, upgraded to version 8.x, and implemented index rollover and lifecycle strategies. This transition reduced disk costs, improved search and indexing performance, and simplified operations.• Designed and executed GitOps-based deployment strategies using Flux to automate and streamline continuous integration and continuous deployment (CI/CD) processes.

• Oversaw and coordinated deployments within internal environments to ensure smooth and reliable application updates and integrations.• Developed a custom exporter in Go to monitor API response times and status, enhancing the visibility and reliability of API performance.• Automated routine tasks such as cleaning up storage accounts and applying Cassandra schemas using Python, significantly reducing manual effort and improving operational efficiency.
