Discovery

Discovery and onboarding

Problem: Too many topics, too many experts, and too little guidance.
Solution: Fewer topics, chosen visually. Trending experts up front. Matcher alongside search.
Result: 3x booking conversion, A/B tested across 50K+ monthly seekers.

Expert Matcher

Guide, do not interrogate

Problem: Search only works when you know what to type.
Solution: A short matcher and a chat. Each expert comes with a reason why.
Result: A second front door to booking, next to search.

Booking

Near one-step booking

Problem: Booking took about 20 steps across several screens.
Solution: One side sheet on web and one bottom sheet on mobile.
Result: 51% of seekers returned to book again.

Supply

Expert profile and onboarding

Problem: Getting an expert live took 2 to 3 hours of setup.
Solution: A short guided flow for profile, topics, and availability.
Result: Supply grew to 800+ experts.

Tokens first, then components

One library, documented to a build-ready spec. Every value is a token, named the same in Figma, CSS, and Swift. Static mocks could not answer how a flow felt in hand, so prototypes moved from sketch to test in days, not weeks.
