Worked on the nextcloud/deck repository to enhance the reliability of board member management by addressing a MySQL-specific deletion error. Focused on backend development and database management using PHP and SQL, the solution involved refactoring the board member deletion process into two distinct steps: first collecting relevant assignment IDs, then deleting assignments based on those IDs. This approach ensured compatibility across MySQL versions and adhered to best practices for handling foreign-key constraints. The update improved data integrity and reduced user-facing errors when removing board members, resulting in a more maintainable codebase and lowering the potential for support issues related to deletions.
