Caleb Kho worked on the ubclaunchpad/forum repository, delivering a focused reliability and security upgrade for document handling. He implemented robust document upload validation, including type and extension checks, file size limits, and enforced course-specific storage buckets to ensure data isolation. Using Python, he refactored backend storage logic to verify bucket existence and improved API error handling by returning precise 422 errors for invalid uploads. Caleb also enhanced error transparency by re-raising original exceptions in the file storage layer, improving diagnosability for callers. His work demonstrated depth in backend development, cloud storage integration, and error handling within a production environment.

January 2025: Delivered a major reliability and security upgrade for document handling in ubclaunchpad/forum. Implemented robust validation for document uploads and course-specific storage buckets, improved API error handling for invalid uploads (422), and enhanced error reporting from storage components to callers. These changes increased upload reliability, enforced data isolation by course, and improved observability, setting the project up for scalable, per-course storage.
