Worked on enhancing the Shubhamsaboo/adk-python repository by delivering a feature focused on robust JSON serialization, particularly for non-ASCII character support. The approach involved updating the _safe_json_serialize function to use ensure_ascii=False, ensuring accurate handling of international content and reducing risks of data corruption. This safer serialization method was also extended to function-call arguments through the _content_to_message_param utility, promoting consistency across the backend. The work emphasized reliability and safe API integration, laying groundwork for future internationalization. Python was used throughout, leveraging skills in backend development and JSON serialization to improve data handling without introducing new bug fixes during the period.
