At Cognizant, I build CI/CD pipelines with Jenkins and GitHub Actions for microservices, cutting release time by 40%. I also manage AWS infrastructure, where I maintained 99.9% uptime and reduced monthly costs by 20%.
I run containerized applications on Kubernetes (EKS) with Docker and Helm, and set up Prometheus, Grafana, and CloudWatch monitoring that helped reduce MTTR by 35%. I also handle blue-green deployments and rollbacks, add automated pipeline tests, and write shell scripts and runbooks to support releases and operations.
