PROFILE

Seven Du

During two months of focused development, Dujinfang delivered two feature-rich contributions across the k2-fsa/sherpa-onnx and TEN-framework repositories. In TEN-framework, Dujinfang built a Python-based script that generates visual graphs from JSON data, streamlining data exploration and analytics by automating visualization tasks. For k2-fsa/sherpa-onnx, Dujinfang extended the C API to support GenerationConfig and Pocket TTS models, enabling fine-grained control over text-to-speech synthesis and broader model compatibility. The work demonstrated depth in C, C++, and Python, with careful attention to API design and usability, resulting in maintainable, extensible features that address real user needs in audio and data visualization domains.
