Worked on the DUNE/sandreco repository to enhance the continuous integration pipeline, focusing on both performance and reliability. Implemented parallelized CI builds by integrating EDEPReader directly from source and configuring installation steps, which enabled up to eight concurrent jobs and reduced overall compile times. Addressed pipeline stability by removing outdated EDEPTree-related configuration from the .gitlab-ci.yml file, eliminating recurring errors and ensuring consistent execution across runs. The work leveraged Shell scripting, YAML, and GitLab CI to streamline build processes and improve feedback cycles. This approach resulted in a more efficient and dependable CI/CD workflow for ongoing development and testing.
