Technical lead and frontend engineer in Chengdu, working around AI-powered video products, React/TypeScript systems, automation, and complex web interfaces.
- AI/LLM workflow and business automation integration
- React/TypeScript performance, complex UI, and video-product workflows
- API/system integrations and small internal tools
- Authorized Windows team cleanup and system maintenance
- Creator/brand campaign planning, shortlist, brief, outreach, and tracking
I work on one system, one critical workflow, or one clearly bounded integration at a time. Every engagement starts with written scope, acceptance criteria, exclusions, and a handoff. I do not promise traffic, revenue, or outcomes outside my control.
