During June 2025, work centered on the SCE-Development/Clark repository, where a prototype feature introduced a backgroundColor field to the user object, enabling user profile personalization through the editUser API. The implementation, developed using JavaScript and full stack development skills, was carefully managed with a reversible approach, as the feature was added and then rolled back to maintain API stability. Although the change was not deployed to production, the process established a clear rollback path and preserved the existing API surface, providing valuable groundwork and clarified requirements for future iterations focused on user personalization and backend extensibility.
