Two-sided marketplace · Sole product designer
Expert help,one tap away
Warmer connected people with experts who had lived through diabetes, cancer, and other life moments. I owned design across mobile, web, and the full funnel, from first visit to repeat booking.

The challenge
Too many topics, too many experts, and too little guidance.
Seekers left before finding the right person. The redesign put fewer topics up front, chosen visually, with trending experts and an AI matcher beside search.

Supply
Expert profile and onboarding
Getting an expert live took 2 to 3 hours of setup. A short guided flow covers profile, topics, and availability. Profiles lead with lived experience, and supply grew to 800+ experts.
System
Tokens first, then components
Every value is a token, named the same in Figma, CSS, and Swift.
Workflow

ProblemStatic mocks could not answer how a flow felt in hand.
