At Meitu, I built backend services from scratch for AI image and video products and built a multi-tenant Credits Platform serving 10M+ users across products including AirBrush and BeautyPlus. I designed its APIs and data models to keep credit balances consistent under high concurrency.

I also led the migration of four core Go services and their databases from Azure to OCI, completing the move in six weeks with zero downtime. I built a low-code configuration platform that reduced configuration release time from three days to 10 minutes.

I'm currently building an AI-powered job search agent with Python, FastAPI, LangGraph, and PostgreSQL. My earlier backend work includes Tencent commerce services and Lazy Audio settlement pipelines handling 500K+ orders per day.
