Cartly

About the project

Cartly blends entertainment and commerce: creators run live shopping streams while viewers browse, preview products in AR and check out without leaving the broadcast. I built the mobile app for both platforms from a single React Native codebase.

The hardest problems were latency and checkout friction. A GraphQL layer keeps stream metadata, inventory and pricing in sync, and a one-tap Stripe checkout converts viewers in seconds — it became the most-used feature in the app.
