Worked on the elevenlabs/elevenlabs-python repository to enhance the reliability of its Python client by addressing multipart audio parsing issues for music endpoints. Focused on backend and API development, the work involved implementing robust detection of audio data start points and supporting both CRLF and LF line endings, ensuring compatibility with a variety of multipart response formats. Comprehensive tests were added to cover edge cases, strengthening the codebase against regressions. By improving the stability and maintainability of the client, these changes reduced parsing-related failures and provided a more dependable integration experience for downstream applications using Python and modern testing practices.
