About Me

I am Zhangkunlong, an engineer focused on shipping AI systems to production, based in Shanghai. I currently work at Meituan on multimodal LLM inference acceleration and long-horizon AI Agent optimization.

I graduated from Southern University of Science and Technology (B.Eng. in Computer Science and Technology, M.Eng. in Electronic Science and Technology). I have contributed pull requests to the vLLM community, published a paper on hardware-aware DNN compression for edge devices (Best Poster Award), and won several competitions on Tianchi and Kaggle.
