McDonald's
Designing key mobile features (Table Service, Game Center) while modernizing the Figma design system—using Variables and Branching alongside engineering to scale feature rollouts fast.
Product Design
Redefining the digital ordering journey for one of France’s most high-volume mobile apps. By resolving critical UX friction points—such as preventing wrong-location orders during Table Service—and designing engaging features like a revamped Loyalty system and the in-app Game Center, I helped drive 215,000 active players, 794K games played, and 5M+ game tokens generated (80% from orders) in the first week alone. In parallel, I modernized the Figma design system with Variables and Branching alongside iOS/Android developers to accelerate feature deployments at scale.

Scope: Design System Architecture & App Design
Eliminating Revenue-Draining Pain Points
At McDonald’s scale, a delay of just a few seconds or a single misstep in the order flow translates directly into lost revenue, store operational bottlenecks, and frustrated customers. My primary focus was identifying and eliminating high-friction operational pain points across key feature rollouts:
Preventing Mislocated Table Orders: A major issue with Table Service was users accidentally selecting the wrong restaurant location before checking in at a table. I redesigned the geolocation and order-confirmation UX to contextually validate store proximity before payment, drastically reducing kitchen errors, order remakes, and lost revenue.
Streamlined Loyalty & Table Service Flow: Re-engineered the in-app Table Service experience and Loyalty redemption loops to require minimal taps. By shortening the time-to-order, we protected throughput during peak meal-time rushes while making reward redemption effortless.

Gamification & System Innovation (Game Center & FC McDo)
Beyond utility, we introduced experiential features designed to turn routine ordering into a habit-building loop while upgrading the technical infrastructure powering the app:
Gamification Engine (FC McDo): Co-designed the Game Center hub and its flagship soccer game, crafting an intuitive interface that seamlessly linked food purchases to gameplay tokens. Every completed order rewarded users with tokens, turning meal purchases into active entertainment.
Next-Gen Figma Architecture: To support multiple design teams shipping features simultaneously without UI drift or file conflicts, I upgraded the mobile design system using Figma Variables for dynamic component tokens (modes, states, spacing) and established structured Branching workflows.
Embedded Engineering Alignment: Worked side-by-side with iOS and Android developers in daily ceremonies, ensuring design tokens mapped 1:1 with native code components for zero-gap execution.
Business Impact & Scale Validation
By prioritizing UX precision and friction removal, the app achieved record-breaking organic engagement—demonstrated by the launch of the Game Center (FC McDo), which went viral in Week 1 alone (prior to any paid media push):
Unprecedented Engagement: Reached 215,000 active players and 794,000 total games played in 7 days.
App Retention Growth: Successfully converted +7% of active app users into Game Center players.
Direct Sales Acceleration: Generated 5M+ game tokens—with 80% earned directly through restaurant orders—and burned 1M+ loyalty points for gameplay (the equivalent of 21,000 cheeseburgers or 11,000 Maxi Best Of menus).
Earned Earned Media: Earned 6 major press coverage features within the first week.
