✶ Full shopping flow, single codebase
Marketplace, cart, checkout, subscriptions, order history, and shipment tracking across iOS, Android, and Web — built once with React Navigation and a shared typed API layer.
✶ JWT auth with silent refresh
Login, password reset, and session persistence with an Axios interceptor that transparently refreshes expired tokens on any 401 and retries the request.
✶ Referral program + wallet
Share-tracked referrals credit a wallet balance usable as a discount at checkout, with a transaction history view.
✶ Brazilian checkout details
CEP lookup and real-time freight calculation, CPF/phone validation, and a coupon engine — the pieces that make Brazilian e-commerce convert.
