Worked on stabilizing the continuous integration pipelines for the apache/incubator-kie-tools repository by addressing a persistent Firefox installation issue within the Docker-based CI environment. Focused on build automation and CI/CD processes, the developer modified the Dockerfile to switch the Firefox archive extraction method from tar.bz2 to tar.xz, ensuring the correct browser version was reliably available for automated tests. This targeted bug fix improved the consistency of test execution and reduced flakiness in pull request validation. The work demonstrated attention to detail in maintaining CI reliability, leveraging skills in Dockerfile configuration and automation to support robust development workflows for the project.
