PROFILE
Ding Zuhao
Worked on the vllm-project/vllm-omni repository, delivering features and fixes across deep learning, image generation, and model deployment workflows. Developed parallel classifier-free guidance (CFG) modes for Bagel and HunyuanImage3 models, leveraging Python and PyTorch to improve multi-GPU scalability and inference throughput. Enhanced documentation and onboarding for new model support, and optimized configuration for performance gains. Addressed reliability by fixing cache merge logic and restoring pipeline integrity for the SenseNova U1 model. Demonstrated strengths in data caching, parallel computing, and technical writing, consistently focusing on maintainability, correctness, and efficient scaling of machine learning pipelines in production environments.
