Worked on the MagaluCloud/magalu repository to enhance the Object Storage List API by implementing robust URL encoding and SigV4-compatible URL construction. Developed a custom encoder in Go to handle AWS S3 URI encoding for list parameters such as prefix, continuation-token, and delimiter, ensuring accurate query string construction and ordering. This approach improved the reliability and interoperability of object listing operations across cloud storage services, reducing encoding-related errors and edge-case failures. The work focused on API integration, SDK development, and advanced URL encoding techniques, laying the groundwork for future improvements in query parameter handling and S3 compatibility within the platform.
