About Me

AI Application Engineer / Python Backend Developer

I am an AI Application Engineer / Python Backend Developer based in Hangzhou / Wuhan, with 15 years of experience in software development and testing, spanning Internet, Telecom, and Industrial sectors. From embedded hardware and automation testing to cloud backend and LLM applications, I excel at transforming complex business requirements into stable, scalable engineering solutions.

In recent years, I have focused on: RAG (Retrieval-Augmented Generation) systems, Defect Detection LLM applications, Python backend development, and Azure cloud deployment. I specialize in planning and implementing technical solutions from 0 to 1, including API design, database modeling, performance optimization, and engineering operations.
