Contributed to the woowacourse-teams/2025-mul-kkam repository by delivering 64 features and resolving 15 bugs over four months, focusing on robust backend systems and secure API development. Built and refined domain-driven features such as JWT-based authentication, OAuth flows, and value object validation, while enhancing CI/CD pipelines for reliable deployments. Leveraged Java, Spring Boot, and SQL to implement RESTful APIs, optimize database migrations, and enforce coding conventions. Improved test coverage and system reliability through integration and unit testing, and addressed performance bottlenecks by refactoring entity relationships and mitigating N+1 queries. Maintained clear documentation and streamlined workflows for maintainable, production-ready code.

Oct 1, 2025For 2025-10, delivered targeted CI/CD workflow optimization for Android and Backend in woowacourse-teams/2025-mul-kkam. Implemented path-based triggers to reduce builds triggered by unrelated changes and shorter feedback cycles. Standardized Android CD workflow by updating default release note paths and release names, improving release traceability and consistency. The changes are captured in commit dcd526afc0d9d5c0cf2d47ddd9dc4bf277e0ef27 with docs: Android, backend cd 파일 경로 추가, and accompanied by updated docs for maintainability and onboarding.
