Worked on the sparcs-kaist/clubs repository to enhance the semester credits system by introducing a dedicated cipher credit entry, focusing on improving attribution and data structure scalability. Leveraging TypeScript and frontend development skills, extended the existing data model to include detailed contributor metadata such as nickname, name, role, role type, and comments. The implementation ensured traceable attribution by linking changes to specific commits, supporting auditability and future enhancements. This targeted feature laid the foundation for standardized, scalable credit entries, enabling more accurate contributor records and facilitating future aggregation and reporting. Delivered a clean, well-documented update with minimal disruption to existing structures.
