What I'm looking for

I’m looking to build and ship agent-driven AI products end-to-end—owning architecture, reliable production ops, and growth workflows—using modern full-stack and cloud-native practices, with room to iterate fast and keep systems dependable.

I’m a Full-Stack AI Engineer with 18 years of software R&D experience, recently focused on AI Agents, full-stack product delivery, and production deployment. I build launch-ready systems by owning architecture from 0-to-1 through core engineering, ops loops, and continuous improvement.

At WUI.AI, I independently led the 0-to-1 design, launch, and ongoing operations of a commercial AI video generation platform. I built an end-to-end AI video production pipeline (Idea/Script → multi-agent orchestration in FastAPI + LangChain/LangGraph → export), an internationalized creation portal supporting 20+ languages, and credit/subscription monetization with reliable async task execution and real-time feedback.

I bring a disciplined engineering loop to agent applications—controlled context management, structured output, tool calling, and hallucination recovery—backed by TDD, CI/CD gates, log-driven troubleshooting, and secure production practices. I’ve also led frontend architecture and team standards at Shanghai Ping An Puhui and managed high-iteration e-commerce frontend systems, combining strong frontend foundations with AI-coding automation skills.
