Profile: https://flows.cv/xiangli

I build products at the intersection of AI, design, and engineering—where great taste matters as much as great models. With rapid progress in LLMs and multimodal AI, I believe the next generation of products won’t just need strong tech—they’ll need the kind of intuition, clarity, and user empathy that comes from thoughtful design.

Right now at Coupang, I'm working on reimagining search with LLMs and image-based ML. We're building smarter, more intuitive search experiences that understand both language and visuals—making it easier for millions of users to find what they love.

Before this, I was at Retool, where I led a major overhaul of our source control infrastructure—improving scalability, cutting stability issues by 80%, and speeding up deployments by 91%. Earlier at Google, I led the Discover content understanding team, applying models like BERT and MUM to deliver fresher, more relevant recommendations.

I'm especially excited about what’s next: AI-native experiences, multimodal interfaces, and the tools that will shape how we build in an AGI world.
