Undergraduate at Tongji University · Shanghai
I’m an undergraduate at Tongji University, majoring in Information Security. I’m mainly interested in security, as well as systems and AI agents.
I do competitive programming: I’m a member of Tongji’s first team to qualify for the ICPC World Finals, and I lead CPCLab, the university’s algorithm association. I’m also a Student Expert at JetBrains, and I spent mid-2026 building agent evaluation environments as an AI infrastructure intern.
