About
AI Solution Builder
I'm an AI Solution Builder focused on turning real business problems into practical AI systems, from enterprise agents and RAG to intelligent search and workflow automation.
My background spans information systems, finance, biostatistics, and data science. Since 2024, I have been building the technical and product judgment needed to connect business needs with modern AI capabilities.
I work across the full solution lifecycle: understanding the problem, framing measurable value, designing the architecture, building the POC, and evaluating whether the system is ready for a real operating environment.
I care about AI solutions that do more than look impressive in a demo—they should be useful, controllable, and able to create measurable value for the people and organizations adopting them.

ETH | Machine Learning Engineer Intern (Nework, CA)
Agentic Multimodal Search System
Built an Agentic Multimodal Search System POC to improve search coverage and relevance, supporting hybrid retrieval and temporal queries. Developed a multimedia indexing pipeline and an LLM query understanding module for NL-to-DSL parsing, fine-tuning domain-specific LLMs to optimize retrieval and server-side performance.
Yale Gerstein Lab | Research Assistant
BioGraphRAG Biomedical Retrieval System
Built a GraphRAG-style biomedical mechanism retrieval system with DAG reasoning constraints to reduce semantic drift. Designed a comprehensive retrieval pipeline integrating Neo4j multi-hop search, semantic index construction, and FAISS reranking to generate traceable mechanism explanations.

对 AI 时代编程语言的感悟
在现在的 AI 时代，如果还抱着过去那种“死磕一门语言、做某个语言的垂直专家”的旧观念不放，就是所谓在用战术上的勤奋来掩盖战略上的懒惰。
Knowledge Management / Learning Systems
关于知识管理的一点反思
最近一段时间一直在快速学习大量新的技术知识。AI、LLM、Agent、系统设计、云计算、软件工程，每天接触很多新的概念。我习惯把学习内容整理到 Notion 里面，通过建立不同层级的页面，把知识按照主题进行分类。
