I designed and built three AI applications through Independent AI Practice: an intelligent procurement system, a GraphRAG knowledge base, and a multi-discipline collaboration system. Each addresses a practical challenge drawn from my engineering work.
For procurement, I designed a LangGraph multi-agent architecture to test automation from requirement analysis to order placement. I also included sandbox isolation and human approval at key decision points.
For engineering standards, I built a knowledge base prototype for cross-modal retrieval and source citation. It reached 92% Context Precision and 95% Faithfulness, with a human-in-the-loop rate under 5%.
Before my AI practice, I worked in process safety and design at Shenzhen Haofeng Technology Development Co., Ltd. and Shenzhen Jutal Machinery Equipment Co., Ltd. I applied HAZOP, designed process and safety systems, and coordinated engineering disciplines; I now bring that closed-loop risk-control approach to AI product design.
