Over two months, Lee Hyunmin developed and enhanced the admin Subject Management backend for the OZ-Coding-School/oz_externship_be_01 repository, focusing on secure, scalable CRUD operations and image upload workflows. Leveraging Django, Django REST Framework, and Python, Lee integrated AWS S3 for thumbnail storage, implemented dynamic dropdown endpoints to streamline admin and frontend processes, and refactored data models to support shared thumbnails. The work included robust access control with updated permissions, improved code structure, and comprehensive documentation updates. These contributions reduced manual data handling, improved data integrity, and enabled faster onboarding for both administrators and developers working with the system.
