About Me

Software engineer with research background in computer vision, now building enterprise .NET solutions and AI-powered medical applications.

Get to know me

I worked at WiseTech Global (the largest SaaS company in freight forwarding) as a .NET Software Engineer (Nov 2024 – Jun 2026), maintaining core components of CargoWise in C#, handling dependency upgrades, thread-safety fixes, DB performance, and UI framework adaptation.

In parallel, I build AI full-stack solutions for medical institutions using MCP + LLM, delivering data visualization and Q&A systems deployed at Beijing Shijitan Hospital, Shanghai Fourth Hospital, and more.

During my studies, I published first-author papers at CCF-A conference (TVCG) and SCI Q1 journal (TIP), and I'm currently revising a TCSVT paper. I won National Scholarship twice, and earned ACM-ICPC silver medal as team captain.
