Rafael Leite developed robust URL encoding and SigV4-compatible URL construction for the Object Storage List API in the MagaluCloud/magalu repository. He introduced a custom encoder to handle AWS S3 URI encoding of list parameters, such as prefix, continuation-token, and delimiter, using Go and focusing on API integration and cloud storage. This work improved the reliability and interoperability of object listing operations by addressing encoding-related errors and edge-case failures. Rafael’s technical approach ensured correct query string construction and ordering, laying a solid foundation for future enhancements in query parameter handling and S3 compatibility within the object storage SDK.
