Strong experience designing CI/CD with GitHub Actions, Harness and Jenkins for build, validation, approvals, release orchestration, rollback and multi-environment deployments. Extensive involvement in cluster operations in AWS Kubernetes (EKS) to deploy microservices with CI/CD system and used Kubernetes cluster to scale up operations of clusters, maintain the cluster services, load balancing, network policies, group Docker containers across different platform.

Hands on experience in writing Terraform IAC modules to manage AWS infrastructure, for automatic creation of RDS instances, VPCs, Autoscaling groups, Load balancers, SQS, S3 buckets. Expertise in production ready, load balancing, highly available, fault tolerant, auto scaling Kubernetes Infrastructure and Microservice Container Orchestration.

Experience in Kubernetes Replication controllers to allow multiple pods such as Jenkins master server in multiple minions.

Managed

Kubernetes charts using Helm, managed Kubernetes manifest files and created reproducible builds of the Kubernetes application.

Experience in Kubernetes templates for various applications like Cassandra, Grafana, Kafka and setting up Kubernetes Clusters for running microservices and pushed microservices into production with Kubernetes backed Infrastructure. Strong exposure in utilizing Jenkins, GitHub Actions as CICD tool and code integration, code delivery and release pipelines.

Experience in using Jenkins pipelines to drive all microservices builds out to the Docker images, stores in Azure Container registry and then deployed to Kubernetes.

Created

Pods, managed using Kubernetes and performed Jenkins jobs for deploying using Ansible playbooks and bitbucket. Installed and configured AWS and Azure plugins locally for seamless integration with Terraform IAC. Experienced in working on Docker hub and Docker swarm, Docker compose creating Docker images and handling multiple images primarily for middleware installations and domain configuration and worked on Docker container snapshots.
