Junhao Zhang (Jay) — Machine Learning & HPC Engineer
ABOUT
I’m Junhao Zhang—Jay for short—a Machine Learning Software Engineer focused on GPU programming, high-performance computing, and advanced systems. I build faster, more efficient machine learning systems—from tuning Llama 2 70B to shipping performance work for Hugging Face, Alibaba & Microsoft. Away from the terminal, I’m usually in the mountains, beneath the waves, or behind a camera.
