- USA Create functions and assign roles in AWS Lambda to run Python scripts, and AWS Lambda using Java to perform event-driven processing. Responsible for maintaining the Enterprise DevOps tools for SCM, Build, Deployment, Package/dependency management, Testing, and Monitoring tools. Set up CI/CD pipelines for Microservices and integrated tools such as GitHub, Maven, SonarQube, Nexus, Docker, and Slack to provide feedback immediately to the different teams on the progress and state of the build Created functions and assigned roles in AWS Lambda to run Python scripts, and AWS Lambda using Java to perform event-driven processing. Used Lambda functions, and Cloud Formation templates to architect Disaster Recovery Plan for a multi-region environment. Used Route 53 to divert the internet traffic to another region in case of disaster. Implemented Ansible to manage all existing servers and automate the build/configuration of new servers. Used Ansible to deploy ELK for automating continuous deployment (CD) and configured Slave Nodes and deployment failure reporting Involved in writing various custom Ansible playbooks for deployment orchestration and developed Ansible Playbooks to simplify and automate tasks. Protected encrypted data needed for tasks with Ansible Vault. Used OpenShift to improve application security by putting admin consoles on different Docker containers accessible only from unusual port numbers. Built complete Configuration Management for the Microservices using Kubernetes, Docker, and Ansible Set up Git repositories and SSH Keys in GitHub for Agile teams Installed and configured Kubernetes for the orchestration of Docker images on AWS using Kubernetes operations. Built Jenkins pipelines to drive all microservices builds out to the Docker registry and then deployed to Kubernetes, Created Pods, and managed using Kubernetes. Commanding expertise in setting up Kubernetes clusters with unparalleled precision and efficiency within the Amazon EKS ecosystem Utilize Kubernetes and Docker for the runtime environment for the CI/CD system to build, test, and deploy. Manage source code repositories such as GitHub by creating branches, put merging pull requests

- Epsilon, USA Worked on integrated AWS Cloud Watch with EC2 instances for monitoring the log files and storing in Cloud Watch logs and used lambda services through Python scripts for taking regular EBS snapshots. Designed an AWS cloud formation template to create VPC. Worked on terraform modules that had version conflicts to utilize CloudFormation during terraform deployments to enable more control or missing capabilities. Wrote templates for AWS infrastructure as a code using Cloud Formation Templates to build staging and production environments with required configurations and set up directory service for integrating with other AWS services. Supported the API development team in creating Ansible playbooks for deploying, integrating, and monitoring their continuous integration environment. Created pipeline to automate microservices deployments in Kubernetes clusters using manifest file or Helm Charts Wrote Ansible Playbooks, and Roles using YAML with different modules to set up Provisioned Dynamic Jenkins Docker slaves using Docker Host for CI/CD pipelines Integrated GitHub webhooks into Jenkins to automate the code check-out process Automated infrastructure provisioning on AWS using Terraform and Ansible Created quality gates in the SonarQube dashboard and enforced them in the pipeline to fail builds when conditions are not met Used VPC, EC2, S3, RDS, Lambda, Route 53, Cloud Formation, and other AWS services and participated in the migration of applications to the AWS platform Continuous Delivery Pipeline. Deployed microservices, including provisioning AWS environments using Ansible Playbooks.
