Developed a safer package cleanup enhancement for the GDATASoftwareAG/vaas repository, introducing a dry-run mode that allows verification before actual deletion of package versions. Focused on backend development using Go, the work involved refactoring the cleanup job to enforce stricter checks on version tags and dependencies, ensuring only eligible packages are removed. This approach reduced the risk of accidental deletions and improved maintainability. Emphasized code quality and readiness for CI/CD integration by leveraging Docker and GitHub Actions. No major bugs were addressed during this period, as the primary focus remained on robust feature delivery and process improvements.
