Jinhee Ryu developed robust backend features for the OZ-Coding-School/oz_externship_be_01 repository, focusing on secure quiz and test question management. Over two months, Jinhee implemented authenticated and authorized APIs for creating, updating, and deleting quiz content, supporting multiple formats such as MCQ, fill-in-the-blank, and short answer. Using Django, Django REST Framework, and Python, Jinhee ensured data integrity through comprehensive serializer validation, bulk operations, and strict permission controls. The work included codebase refactoring, improved test infrastructure, and integration of tools like Black and MyPy, resulting in maintainable, scalable APIs that streamline frontend integration and support ongoing project milestones.
