Senior Frontend Architect and Tech Lead driving performance, scalability, and developer productivity.
ChinaWhat I'm looking for
I am a Senior Frontend Architect and Tech Lead with 10+ years building high-traffic systems at Alibaba and Didi. I specialize in engineering infrastructure, low-code platforms, and frontend performance optimization.
I led teams to build frontend CI/CD pipelines, foundational component libraries, and automated testing from scratch, and architected service orchestration platforms with ReactFlow. I transformed multi-repo architectures into monorepos and reduced first-screen loading times significantly.
My work on Nantianmen created a plugin-based intelligent assistant with dynamic annotations and event-driven plugins, delivering high self-service and resolution rates and dramatically reducing support load. At Didi I designed the FDE frontend engineering solution, standardizing and extending the R&D process across 50+ connected applications.
I focus on measurable outcomes—reducing bug rates, improving R&D efficiency (~25%), and eliminating backend hardcoding—while enabling teams to move faster and maintain large-scale applications with lower technical debt.
