Hiroki Watanabe contributed to traPtitech/Jomon by building robust backend features and improving API reliability over a three-month period. He delivered server-side pagination and input validation for the Requests API, using Go and YAML to implement limit and offset parameters, enhance error handling, and update Swagger documentation. Watanabe also fixed creator-based filtering in GetRequests, expanded test coverage, and stabilized builds through Go module management. In June, he developed a full CRUD Partition Management API and standardized OpenAPI documentation, refactoring schemas and harmonizing terminology. His work improved data accuracy, maintainability, and integration consistency across the Jomon API ecosystem.

Dec 1, 2024December 2024 (traPtitech/Jomon) focused on reliability and correctness of the GetRequests flow and accuracy of creator-based filtering. Implemented a critical bug fix for RequestQuery: CreatedBy was not populated; restored and ensured proper filtering by creator in GetRequests. Strengthened GetRequests stability and coverage by expanding tests with pagination (Limit/Offset), refining error handling for negative values, and tidying dependencies to ensure consistent builds. Included code style adjustments to meet formatting standards. These changes reduce regression risk, improve API data accuracy for users/admins, and enhance CI/build reliability, delivering measurable business value.
