During September 2025, this developer enhanced the dotCMS/core repository by delivering multipart upload support for the Job Queue API, focusing on improving API usability and the overall developer experience. The work involved designing a new multipart parameter schema and updating the JobQueueResource to accept multipart submissions through a dedicated upload endpoint. Comprehensive documentation updates were made to Swagger and OpenAPI specifications, ensuring that the new workflow was clearly described and accessible to other developers. Utilizing Java and YAML, the developer concentrated on backend and API development, providing clear usage guidance and expanding the flexibility of job queue submissions without introducing new bug fixes.
