Jinhyuk Kim developed core backend features for the woowacourse-teams/2025-Todok-Todok repository, focusing on robust API design, secure authentication, and scalable discussion management. Over four months, he delivered user registration, nested comment workflows, moderation tools, and personalized endpoints such as the User Liked Discussions API. His approach emphasized test-driven development, code convention alignment, and iterative refactoring to ensure maintainability and reliability. Using Java, Spring Boot, and SQL, he implemented features like per-user view tracking with cooldowns and optimized query performance. Kim’s work addressed data integrity, observability, and deployment safety, resulting in a well-structured, production-ready backend system.

Oct 1, 2025Month 2025-10: Delivered the User Liked Discussions API for woowacourse-teams/2025-Todok-Todok. Implemented an API to retrieve discussions liked by the current user with pagination, including a new response DTO, service method, and controller endpoint, plus repository support for querying liked discussion IDs with cursor-based pagination. Also added tests and Swagger API documentation. Through iterative refinement this month, pagination strategy was updated to support fetching all liked IDs and enhanced naming, with corresponding test and documentation updates. These efforts deliver a concrete path to personalized content and efficient retrieval, improving user engagement and system scalability.
