PROFILE
Billishyahao
Yahao He developed and integrated advanced deep learning features across several open-source repositories, focusing on expanding hardware compatibility and optimizing model training workflows. In ROCm/Megatron-LM, Yahao enabled Qwen2 model pretraining with end-to-end orchestration and detailed documentation, streamlining both single-node and multi-node experiments. For huggingface/torchtitan and ROCm/vllm, Yahao contributed GPU benchmarking metrics and enhanced DeepSeek model serving with performance optimizations using Python and PyTorch. In unslothai/unsloth and unslothai/unsloth-zoo, Yahao added AMD ROCm and HIP device support, aligning multi-GPU workflows and reducing vendor lock-in. The work demonstrated depth in distributed systems, GPU programming, and high-performance computing.
