Kosun Je worked on the woowacourse-teams/2025-feed-zupzup repository, establishing the backend foundation with Gradle and Java, and automating development workflows using GitHub Actions and Discord webhooks to streamline team communication. He refactored the like-buffer workflow by introducing REQUIRES_NEW transaction propagation in Spring Boot, ensuring reliable and consistent buffer flushes under concurrent access. Kosun also improved project documentation by restructuring the README with HTML for better onboarding and contributor clarity. His work focused on backend development, CI/CD automation, and documentation, demonstrating depth in repository management, transactional integrity, and cross-team collaboration over a three-month period without reported bug fixes.

August 2025 monthly summary for woowacourse-teams/2025-feed-zupzup. Focused on reliability and data integrity of the like-buffer workflow through a transactional isolation refactor. Key achievement delivered a Feedback Like Buffer Transaction Isolation feature that refactors transactional propagation to REQUIRES_NEW, ensuring the buffer flush runs in its own transaction and reducing cross-transaction contention. This aligns with the v1.1.1 release (commit ddc51f43cd65b53fa92ee779b53ed66ba76f06aa) and supports more consistent like counts under high concurrency.
