About

A product designer who grew up in marketing.

I'm Ting Ting — a Senior Digital Product Designer with 15+ years spanning brand strategy and user experience. I design digital products and experiences that are measured in conversion, retention, and revenue, not just aesthetics.

My specialty is global-to-local translation — adapting global platforms for APAC markets, where language, merchandising logic, and shopping behavior all differ. I've led this work for Costco and Melaleuca, partnering daily with product, engineering, and marketing.
