Cheol Won
Over a two-month period, contributed backend features to the woowacourse-teams/2025-bom-bom repository, focusing on data integrity and user engagement. Developed the ArticleReadHistory entity and monthly ranking preservation logic using Java, SQL, and Spring Data JPA to enable accurate tracking of article reads and maintain historical analytics for user profiles. Subsequently, implemented the Continue Reading Shield feature, introducing shield entities and lifecycle management to help users preserve reading streaks across missed days. Emphasized robust database design, integration testing, and unit testing throughout both features, ensuring reliable monthly resets and supporting personalized dashboards without introducing critical bugs during the development cycle.
