During two months contributing to the bytedance/deer-flow repository, HetaoBackend developed and refined backend systems supporting cross-channel instant messaging, secure file handling, and configuration-driven runtime behavior. They implemented asynchronous integration with Feishu, Slack, and Telegram, enabling robust task processing and channel-specific configurations using Python and Asyncio. Their work included refactoring the backend into modular layers, introducing configuration versioning, and enhancing system security through improved path validation. HetaoBackend also addressed memory privacy by preventing ephemeral file uploads from persisting in long-term storage. The engineering demonstrated depth in backend development, API integration, and maintainability, with comprehensive testing and documentation throughout.
