Hi there, I'm Dexter Ding (Jiahua DIng) 👋

AI Engineer focused on Large Language Model (LLM) training, inference optimization, and agentic AI systems. Currently developing expertise in distributed fine-tuning (LoRA/DPO), GPU kernel optimization (CUDA/Triton), and Agentic AI frameworks (LangChain, Coze, AutoGen). Combines solid ML theory, PyTorch engineering, and system-level optimization to build scalable, high-efficiency AI solutions.

"Building a complete stack understanding from model math to GPU execution pipeline, and from fine-tuning to intelligent agent orchestration."
