During March 2025, Peh worked on the CAUCSE/CAUSW_backend repository, delivering a club and circle role delegation management feature that enhanced RBAC-driven workflows for administrative flexibility. By implementing and validating delegation logic in Java with Spring Boot, Peh enabled accurate multi-role handling and reduced friction for circle admins by relaxing circleId requirements. The work included targeted bug fixes to ensure correct permission states, such as explicitly removing the COMMON role during delegation when users held multiple roles. Peh also improved codebase hygiene by cleaning up delegation-related annotations, supporting maintainability and future enhancements in backend development for user permissions.
