Worked on the innovationacademy-kr/Cabi repository, delivering end-to-end backend features for presentation slot management and scheduling. Focused on refactoring legacy code, implementing robust API versioning, and introducing admin-only access controls to streamline governance. Leveraged Java, Spring Boot, and Nginx to build secure, testable RESTful APIs, with enhancements in date and time handling, batch processing, and DTO-driven service layers. Improved reliability through expanded test coverage, authentication and authorization fixes, and deployment automation using Docker and shell scripting. Addressed technical debt by modernizing scheduler architecture and optimizing database queries, resulting in a scalable, maintainable foundation for ongoing feature development.
July 2025 highlights for innovationacademy-kr/Cabi: Delivered major enhancements to Presentation Slot Management, tightened reliability of slot availability and registrations, and migrated scheduling to a dedicated presentation-slot scheduler, alongside deployment and infrastructure improvements that boosted reliability and rollout speed. Key bugs addressed include a date boundary edge-case where adding a month could misinterpret December as January, now resolved. Overall impact: improved user experience for event registrations, reduced scheduling errors, and faster, safer deployments. Technologies demonstrated: backend refactoring, read-only transactional optimizations, scheduler architecture redesign, deployment automation, and AWS SDK upgrade.
