Worked on the cloudogu/jenkins repository to deliver security and compatibility upgrades alongside workflow improvements for the Jenkins CI server. Focused on updating the Java base-image and OpenJDK tooling within Dockerfiles, the work enhanced the security posture and ensured up-to-date dependencies. Improvements to the build and release process were achieved by refining Makefile management, integrating BATS and Go tools to streamline continuous integration workflows. Emphasized clear versioning and release traceability through consolidated changelogs and release notes. Utilized skills in Docker, Java, and shell scripting to create a more reliable, maintainable CI/CD pipeline without addressing explicit high-severity bugs during this period.
