Jiyoung Yoo developed and enhanced the backend for the OZ-Coding-School/oz_externship_be_01 repository, focusing on robust content and notice management features. Over two months, Jiyoung designed and implemented end-to-end APIs for posts and notices, integrating Django, Django REST Framework, and AWS S3 for cloud storage. The work included building serializers, pagination, and admin endpoints, as well as handling file uploads and data validation. Jiyoung addressed complex data relationships, improved code organization through extensive refactoring, and ensured reliability with comprehensive unit testing. These efforts resulted in improved data integrity, streamlined content workflows, and a maintainable, scalable backend architecture.
