Shin Yonggi contributed to the innovationacademy-kr/Cabi repository by engineering backend features that enhanced presentation engagement and data integrity. Over five months, he developed and refactored RESTful APIs and service layers in Java and Spring Boot, introducing end-to-end support for presentation likes, robust pagination, and DTO mapping with MapStruct. His work included implementing idempotent like/unlike logic, automatic timestamp management, and exception handling to ensure reliable analytics and error reporting. By reorganizing DTO structures and improving repository patterns, Shin enabled maintainable code and efficient data retrieval, while targeted bug fixes and documentation updates supported onboarding, collaboration, and long-term system stability.

Jun 1, 2025June 2025 — Cabi backend: Strengthened the Presentation Like System to ensure data integrity and reliable engagement analytics. Delivered idempotent like/unlike behavior to prevent duplicates and added explicit exception statuses for duplicate and non-existent likes. This reduces edge-case errors in production and improves consistency of engagement metrics. Work is tracked via two commits addressing #1726, enabling easier maintenance and auditability.
