At 上海识装信息科技有限公司（得物App）, I developed an APM-based user journey diagnostic agent that correlates routes, page performance, call chains, and error stacks to produce evidence-backed diagnostic reports. It helped improve the team’s troubleshooting efficiency by 20%.
I also worked on the front-end platform’s monitoring SDKs, including Web and Node monitoring and resource-loading retries. I redesigned the SDK architecture around modularity and a publish-subscribe pattern, and developed a command-line tool for uploading SourceMaps.
For the live streaming application, I completed an architecture migration from Vue3 to React Umi. The migration improved the code quality score from 63.38 to 78.77, reduced code volume by about 24.26%, and lowered code duplication from 3% to 0.31%.
In independent projects, I built an enterprise RAG knowledge and question-answering platform with Vue 3, FastAPI, LangChain, and LangGraph, and developed a full-stack background-check SaaS platform using Egg.js and MySQL. Earlier, I worked on education products, including learning features for 80W+ students and online live classes for 10W+ learners.
