The Mile 🙌 live shopping

The Mile — a creator-commerce mobile app (iOS & Android, React Native) with live shopping. I led end-to-end product design: user flows, UI, design system and component library. Orders grew +300% in the app’s first year.

Role: Senior Product Designer — end-to-end product design. Context: The Mile is a creator-commerce mobile platform (iOS & Android, React Native) where creators sell through their own storefronts and live shopping. I owned the product design across the app. Scope: User flows, UI, design system and component library for both platforms. Process: Design built hand-in-hand with the React Native implementation: one component library serving iOS and Android, so design and code stayed consistent as the app evolved.
Key design decisions Deliverables: Full app design, design system, component library, flows and screens for live commerce. Result: Orders grew +300% in the app’s first year.
The Mile App & Web site + Brand System
The Mile App & Web site + Brand System
A live shopping experience where video and product action coexist: watching never buries the buy flow. Creator storefronts with enough flexibility to feel personal without breaking the design system. One cross-platform component library instead of separate iOS/Android designs, keeping shipping fast for a small team.
