• Self-Service Access Management: Led the design and implementation of a self-service access management system. Leveraged APIs from multiple tools, ensuring accountability through database records and JIRA tickets. Resulted in a 90% reduction in time and effort spent on access management tasks.
• EKS Cluster Setup: Orchestrated the setup of EKS cluster using Terraform, including spotinst-managed node groups, RBAC for microservices, and deployment of various devops-managed kubernetes services. Integrated the Terraform code with a centralized MySQL database for RBAC management.
• Zero-Downtime Kubernetes Migration: Contributed to the plan and execution of migrating 100+ microservices from a self-managed Kubernetes cluster (v1.16) to EKS (v1.24).
• Ingress Controller Setup & Migration: Evaluated various Kubernetes ingress controllers (e.g., Nginx, f5-nginx, ALB, Traefik) and successfully migrated all the microservices from nodeport-based routing to Traefik ingress-controller.
• Observability Setup and Optimization: Setup Prometheus and Grafana monitoring stack for comprehensive system observability of the kubernetes environments. Successfully optimized Prometheus resource utilization and performance, achieving a roughly 60% reduction in memory consumption.
• Release Process Efficiency: Automated and streamlined release stages in collaboration with the release team, improving deployment efficiency. Also implemented nightly deployment of microservices.
• Incident Management: Actively participated in on-call rotations, ensuring prompt resolution of production incidents to maintain service uptime.

• Microservices Infrastructure Setup: Facilitated infrastructure setup for new microservices, encompassing AWS, Kubernetes, and Jenkins configurations.
• Production Release Management: Independently managed production releases for a period of 3 months and documented the complete process. Automated manual steps and provided knowledge transfer to an external vendor to handle the daily releases.
• Jenkins Ownership and Upgrades: Led seamless upgrades of multiple Jenkins servers hosting 100+ jenkins jobs.
• Terraform & Ansible Code Refactoring: Refactored the Terraform and Ansible codebase of a self-managed Kubernetes cluster, adopting a module-based approach. Enhanced codebase modularity, reusability, and maintainability.
• Credential Rotation: Executed database credential rotations across 80+ microservices and monolith servers, coordinating with application teams to ensure smooth transitions.
• Data Refresh Automation: Developed bash scripts to automate production data refreshes for lower environments, cutting execution time by 80%. Supported various data sources such as RDS, Aerospike, and Solr.
• CI/CD Tool Evaluation: Collaborated with an external vendor to evaluate Spinnaker as a potential CI/CD solution.
• Kubernetes Cost Tracking: Implemented team-wise infra cost tracking for Kubernetes resources.
