Worked on the BCSDLab/KOIN_API_V2 repository to enhance backend reliability and maintain legacy compatibility for shuttle bus scheduling features. Applied backend development and database querying skills using Java and the Spring Framework to address two critical bugs. Improved route filtering logic to ensure only valid weekday routes are included and corrected time calculations so departure times always precede arrivals, increasing schedule accuracy. Later, implemented a targeted fix for legacy API endpoints by defaulting weekend bus route direction to '등교' when arrival times are missing, preserving compatibility for existing clients. All changes were delivered with clear commit traceability and minimal production risk.
