Leonard Baath developed a Permissions Deletion API for the fsek/WebWebWeb repository, enabling administrators to fully remove permission entries based on action and target. He designed and implemented both the API route and the supporting database schema, ensuring that deletions are thorough and maintain data integrity. Working primarily in Python, Leonard applied his skills in API development, backend engineering, and database management to deliver a solution that streamlines permission cleanup tasks. He also refined error messaging within the deletion flow, reducing confusion for users and lowering support overhead. The work demonstrates careful attention to technical detail and business requirements.
