I'm an undergraduate student at Northwest A&F University (NWAFU), majoring in Mathematics and Applied Mathematics. My interests lie at the intersection of AI and practical development—specifically, I’ve been diving into deep learning, machine learning, and large language models (LLMs). Lately, I’ve been focusing on honing skills in Agent systems, Retrieval-Augmented Generation (RAG), and LLM fine-tuning. Beyond AI, I also work on general app/software/web development.

Open Source:
- Contributed to SurfSense (a GitHub project) by adding support for Chinese domestic LLMs, integrating Chinese search engines, and implementing front-end internationalization.
I’m passionate about learning by doing and love collaborating on open-source projects—whether it’s refining AI workflows, building user-friendly tools, or solving real-world problems with code. Feel free to reach out if you’re working on something interesting, or if you want to chat about ML, LLMs, or development!
