  • Pulled the code from Bitbucket to Cloudbees Jenkins using Git plugin’s and build the code using tools like maven and ant.
  • Integrated Sonarqube with Jenkins and bitbucket for the dynamic code analysis and set quality profiles and quality gates for the team.
  • Deployed build artifacts during the jobs into the JFrog Artifactory and tagged artifacts by build number.
  • Experienced in branching, build and release strategies in GIT for different projects.
  • Developed build and deployment standards with inputs from development, operations, and IT security.
  • Used ANT and MAVEN as build tools on Java projects for the development of build artifacts.

• • Used the http methods PUT, POST, GET, DELETE, etc., to call the rest api’s for various processes done via UI.
  • Created a Jenkins job with parameters and configured it to pass Project Name & Keys arguments for Jenkins, Bitbucket, Sonarqube and Artifactory applications.
  • Scheduled the job to run periodically to read the customer intake forms and create the new projects accordingly across the CICD applications.
  • Configured each project permissions exclusively to the customer teams depending on their AKMID.
  • Worked with the customers in resolving the integration issues between their Jenkins Jobs across other platforms.
  • Installed and configured various community and tier 1 plugins and Integrated Atlassian Bitbucket with Jira using OAuth Authentication, for linking Jira tickets for code commits.

• Expert in building docker images depending on the team’s requirement and deployed them to artifactory server:

• • Automated the docker image creation by configuring a Parameterized Jenkins jobs with parameters.
  • The parameterized job will take a json file input, build the Dockerfiles and store them Bitbucket repo and the downstream job will build the images and push them to Jfrog artifactory.
  • Written and built custom Dockerfiles to create docker images from scratch. Developed alpine linux and centos images and used them as docker containers.
