What I'm looking for

I'm open to remote full-time or contract roles with US and international teams.

At Taidou Technology (Shanghai) Co., Ltd., I worked on AI-driven ad-delivery applications, Agent orchestration systems, and management dashboards. I developed conversational tools with React 19, Next.js, and LangGraph for natural-language ad creation and strategy generation.

I also helped build Python Agent and NestJS service layers, including conversation summarization and context compression that reduced token consumption by approximately 60% in specific scenarios. I established a Monorepo architecture and implemented a Jenkins and Docker deployment pipeline that reduced build times from around 20 minutes to 4–5 minutes.

At OpsMate AI, Inc., I participated in building an industrial AI Agent management platform and led its frontend architecture upgrade and streaming interaction system. The work included Agent workflow visualization and a migration strategy designed for a zero-downtime transition; frontend optimizations reduced initial page load latency from approximately 4200ms to 820ms.

Earlier, I worked on medical imaging and remote consultation products at Shanghai Xingmai Information Technology Co., Ltd., and on ERP and automotive design risk management systems at Shanghai Tonglin / Shanghai Ruizhuo. At Aeris Health, I contributed to customer and staff portals and two FastAPI backends, owning the policy-based IAM core.
