Two years modernizing France's most downloaded utility app. Homepage, onboarding, maps, and the groundwork for a design system.

In 2014, PagesJaunes served 15M+ monthly visitors but felt stuck in web directory logic. The mobile apps existed, had millions of downloads, but the experience was heavy. Navigation felt dated. The challenge: make it faster, cleaner, more useful, without breaking what worked for existing users.

I joined as Product Designer working on web, partnerships (TheFork, Renault R-Link), and login flows. In 2015, I became UI Team Lead: coordinating 4 designers, owning the mobile app redesign, and running weekly syncs with iOS/Android devs.
Product Designer. Web, partnerships, login flows.
UI Team Lead. 4 designers. Major app release.
Retention features. System foundations.
Concrete deliverables across iOS, Android, web, and Android Wear.

A conversational greeting reframes search from directory lookup to problem-solving. Users act faster when the interface feels personal.

Non-blocking animations at first launch. CAAnimation on iOS, Material transitions on Android. Tested in Paris UX lab.

Three modes: walk, drive, transit. The interface adapts to the user's choice. Built on Mappy API with handoff to external navigation apps.

History and Favorites turn one-time searches into retained value. Each saved business is a reason to return.

Wearable task flows: search then call, or search then navigate. Two jobs, two paths, minimal taps.

Component audit across iOS, Android, and web. Identifying inconsistencies, documenting patterns, building the roadmap for "Yellowstrap".
22M users have muscle memory. Radical changes confuse them. Small, clear improvements work better.
People search for a plumber when they have a leak. Every millisecond counts. Especially on 3G.
iOS, Android, web, Wear: each platform has its own constraints. Shared patterns require constant negotiation.
Big company, many stakeholders. Sometimes the hardest part isn't design, it's alignment.
