AI Algorithm Engineer @ Li Auto.
I build practical AI systems that connect algorithm research with production engineering. My work spans computer vision, LLM training and post-training, retrieval systems, and workflow orchestration. Due to the confidential nature of my work, this profile focuses on public technical explorations, reusable engineering patterns, and open-source work.
PyTorch · Computer Vision (YOLO / DETR / ViT / CNN) · LLM Fine-tuning / Post-training / Reinforcement Learning · Retrieval Systems (Embeddings / BM25 / Hybrid Retrieval / Reranking / GraphRAG) · LangChain / LangGraph / Dify · Python / SQL / Data Pipelines
- Training and adapting vision and language models for practical tasks.
- Building retrieval and knowledge-grounded generation pipelines for real-world use.
- Exploring workflow architectures for higher-accuracy reasoning systems.
