- Led deployment ownership, planned infrastructure, and collaborated with development teams for multiple microservices running in Kubernetes environments.
- Worked closely with development, QA, and SRE teams to drive deployment decisions, standardize infrastructure practices, and support product release activities across multiple environments.
- Optimized deployment processes by integrating ArgoCD as the central GitOps platform, enabling stable rollouts through defined sequencing dependencies and effective secret management for 25 microservices.
- Evaluated Terraform and Terragrunt to design and standardize infrastructure as code (IaC) strategy, facilitating secure and scalable patterns embraced by engineering teams.
- Delivered modular IaC foundation that enhanced deployment reliability, minimized manual operations, and standardized environment provisioning across platform.
- Optimized existing Kubernetes/OpenShift environments by managing deployments, onboarding new microservices, and performing configuration updates and application health validation.
- Improved Kubernetes resource utilization by tuning CPU/memory requests and limits, optimizing HPA configurations, and right-sizing worker nodes for microservices workloads.
- Worked on cloud cost optimization by identifying idle EC2 instances, unused EBS volumes, and over-provisioned Kubernetes workloads, helping reduce unnecessary infrastructure usage across environments.
- Enhanced release automation by designing automated image promotion workflows and resolving real-time issues, improving release speed, consistency, and operational reliability.
- Designed and implemented operational pipelines to reduce deployment-related issues and improve overall release stability.
- Led migration of 40+ microservices from Artifactory to IBM ICR, achieving zero-downtime cutover while enhancing security, scalability, and image governance.
