Worked on the uclouvain/osis-admission repository to enhance the reliability of database initialization during deployment. Addressed a critical issue by updating the migration logic to ensure the admission_program_managers group is automatically created if it does not already exist, thereby preventing errors when initializing a fresh database. This solution reduced the risk of startup failures and minimized manual intervention during environment setup. The work focused on backend stability, leveraging Python and Django ORM for database migration tasks. By concentrating on this targeted bug fix, the developer contributed to smoother onboarding of new environments and improved the robustness of the deployment process.
