During May 2025, this developer delivered four features across the ucsb-cs156-s25/proj-courses-s25-03 and ucsb-cs156/proj-courses repositories, focusing on backend enhancements and data export reliability. They implemented a new General Education Areas API endpoint and refactored curriculum modules for improved readability using Java and Spring Boot. The developer overhauled CSV export functionality by introducing a dedicated service for CSV line generation, decoupling logic from controllers, and updating tests with JUnit and Mockito. These changes reduced code coupling, improved maintainability, and strengthened test coverage, resulting in a more robust and efficient workflow for course data retrieval and export.
