Jaehoon Lee contributed to the Today-Story/TRIT-BE repository by delivering robust backend features and refactoring efforts focused on API performance, data modeling, and deployment reliability. Over two months, he enhanced DTO hygiene, modularized service layers, and optimized database queries using Java, Spring Boot, and Liquibase. His work included evolving the coupon management system, improving authentication flows, and strengthening CI/CD pipelines for safer migrations. By addressing N+1 query issues, standardizing parameter handling, and expanding test coverage, Jaehoon improved both system maintainability and scalability. The depth of his engineering ensured stable feature delivery and a more resilient, production-ready backend architecture.

August 2025 (Today-Story/TRIT-BE) delivered substantive backend refactors, feature expansions, and reliability improvements across the TRIT-BE stack, enhancing data projection, mapping accuracy, artifact handling, and deployment reliability. The work reduced risk in migrations, improved API stability, and expanded location, search, and settlement capabilities while strengthening CI/CD processes and test coverage.
