Jiyoon Yoon developed and enhanced the backend for the OZ-Coding-School/oz_externship_be_01 repository over two months, focusing on robust content management and API reliability. Using Django, Django REST Framework, and Python, Jiyoon implemented end-to-end APIs for notices and posts, including admin features, pagination, and file upload handling with AWS S3 integration. The work included database modeling, serializer design, and comprehensive test coverage, addressing multipart data, image processing, and data integrity across both the database and cloud storage. Through extensive refactoring and code organization, Jiyoon improved deployment predictability, reduced production incidents, and accelerated feature delivery for the community module.
