Gabriele Sirri enhanced the DUNE/sandreco repository by optimizing its continuous integration pipeline to improve build speed and reliability. He introduced parallelized CI builds, enabling up to eight concurrent jobs, and integrated EDEPReader directly from source, streamlining installation and reducing compile times. Using Shell scripting and YAML within GitLab CI, Gabriele addressed pipeline stability by removing outdated EDEPTree references, which had previously caused execution errors. His work focused on making the CI process more consistent and reusable, demonstrating a solid grasp of CI/CD and DevOps practices. The changes provided measurable improvements in feedback cycles and overall pipeline robustness.
