Raphaël Slagmolen focused on improving the reliability of database initialization for the uclouvain/osis-admission repository. He addressed a critical issue where the admission_program_managers group might not exist during a fresh database setup, which previously caused migration failures. By enhancing the migration script using Python and Django ORM, he ensured the group is created if missing, thereby preventing startup errors and reducing deployment risks. His work centered on database migration and robust environment onboarding, contributing to smoother deployments and minimizing manual intervention. Over the month, Raphaël delivered a targeted bug fix that deepened the stability of the project’s initialization process.
