07.2016 - 02.2019
- Implemented a Continuous Delivery pipeline with Docker, Jenkins and GitHub and AWS, whenever a new GitHub branch gets started, Jenkins, our Continuous Integration server, automatically attempts to build a new Docker container from it, The Docker container leverages Linux containers
- Created Docker images and deployed them on the Cloud.
- Was a part of the build and design of the DevOps Reference architecture i.e., Continuous integration pipeline for the Projects (Builds, testing, deployment, matrices collection)
- Strong working experience on Automate system configuration of application servers using configuration management tools like Docker and Chef.
- Helped applications with onboarding to openshift
- Implemented Terraform modules for deployment of various applications across multiple cloud providers and also configuring, managing the infrastructure
- Proficient in Writing Terraform templates, Chef Cookbooks, recipes and pushed them onto Chef Server for configuring EC2 Instances
- Involved in implementing deployments into AWS EC2 with the help of Terraform
- Actively working on Dockerizing the applications and deploying them to the kubernetes clusters
- Responsible for Linux application server’s administration and security setup of the servers
- Have written python scripts to automate the application restart with reboot and managing users on the servers
- Automated and Integrated the CICD pipeline with different scripting like bash, shell and Python
- Automated build and deployment process with Jenkins and Maven, eliminating 80% of manual work
- Administering and managing the work with Kanban
- Setting up and introducing the deployment processes and advising on best practices
- Working on the logging and monitoring tools like Cloudwatch, cloud trail, ELK and Splunk
- Working on POC for validating the best tool to scan the application security like Checkmarx
- Automated the java and mean stack projects end to end CICD pipelines which includes build, run tests, static code analysis, publishing to S3 and Jfrog Artifactory, spin-up infrastructure on the fly, deployment and running the smoke tests
- Worked on Microsoft deployment tool (octopus) implemented and automated the Microsoft automated deployments for multiple projects
- Worked on infrastructure as code using Ansible which would manage the infra automation like provisioning and teardown
- Worked on automating the pipeline, when a dev lead creates a project from the console UI, it would automatically create the necessary infrastructure, users and permissions for the project (like creating the project and repos in Bitbucket, users/groups in active directory and giving the permissions to all the necessary tools like Git, Jenkins, version one etc., Creating necessary jobs in the deployment tool i.e., Rundeck
- Design and implement a Git flow process to integrate JIRA/Jenkins to GIT/Stash and enable quality check and triggers.
