Over two months, contributed backend development to OZ-Coding-School/oz_externship_be_01, focusing on a comprehensive user authentication system. Built login, signup, email and phone verification, and social login features using Django, Django REST Framework, and Redis. Introduced a SocialUser model to link social accounts and integrated authentication endpoints, including Kakao and Naver. Enhanced onboarding by implementing email-based authentication with role-aware responses and phone verification via Twilio, storing codes in Redis. Enabled profile image uploads during signup with AWS S3 integration. Refactored serializers and views for maintainability, improved code quality with formatting tools, and expanded test coverage for authentication flows.

June 2025 (backend for OZ externship): Delivered a robust User Authentication System within OZ-Coding-School/oz_externship_be_01, including login, signup, email verification, phone verification, and social logins (Kakao, Naver). Introduced a SocialUser model to link social accounts and wired social auth into core flows. Implemented related auth APIs and significantly reorganized views/serializers for maintainability. Fixed a critical NullPointerException during comment creation by ensuring SocialUser linkage initialization. Performed code quality improvements (refactoring, formatter) and expanded URL coverage. This work enhances secure onboarding, reduces time-to-first-use for new students, and provides scalable support for social sign-ins and account linking.
