At TCS, I designed Jenkins and Harness CI/CD pipelines for Java microservices and REST APIs, supporting reliable, versioned deployments in a banking domain.
I managed production deployments across AWS EKS and OpenShift, troubleshooting pod, image-pull, and resource issues. I also maintained Terraform modules with S3 and DynamoDB remote state locking for multi-environment provisioning.
For application releases, I used Helm charts and Kubernetes manifests, including environment-specific Helm configurations, upgrades, and rollbacks. I monitored application and infrastructure health with AWS CloudWatch and Kubernetes monitoring, and used MongoDB Shell for database-level troubleshooting and root cause analysis.
Earlier at TCS, I containerized applications with Docker and deployed them to AWS EC2 and ECS. CI/CD validation gates and controlled release workflows reduced production deployment failures by ~30%, while restructured DevOps documentation and runbooks improved team onboarding efficiency by 40%.
