Worked on the Khan/jenkins-jobs repository to enhance CI/CD reliability and streamline deployment workflows. Developed a GraphQL safelist extension using Groovy scripting, enabling Jenkins-created ZND deployments to proceed without manual intervention and reducing deployment failures. Addressed a deployment issue by refining the safelist logic, ensuring queries from manually created ZNDs were accepted. Improved frontend deployment automation by temporarily allowing non-master branches in Jenkins, supporting the decoupling of frontend code. Fixed a Jenkins Groovy sorting bug by introducing a helper function to resolve branch names accurately. Demonstrated expertise in Groovy, Jenkins Pipeline, and DevOps practices throughout the two-month period.
