About

I’m Kathrine Huang, a Senior Product Designer currently designing at Poshmark, where I focus on building AI-powered seller tools, livestream commerce experiences, and scalable marketplace systems. I specialize in turning complex workflows into intuitive, high-impact product experiences that drive both business growth and user delight.

Over the past 8+ years, I’ve designed across e-commerce, mobility, social commerce, and internal platforms — from launching livestream shopping experiences and AI listing tools at Poshmark, to designing rider experiences at Spin, and leading internal product initiatives at eBay. My work sits at the intersection of strategy, systems thinking, experimentation, and storytelling.

I care deeply about creating products that feel both thoughtful and human. Whether I’m simplifying seller workflows, improving onboarding funnels, or designing AI-assisted experiences, I’m always asking:
