Cross-Platform Loyalty App Development

I’m ready to turn a clear product vision into a fully functioning cross-platform loyalty app built with React Native. The finished application must look clean and modern and follow a yellow-and-black palette throughout every screen.

Here’s the scope I have in mind:
• Design & Prototype
– Produce UI/UX mock-ups for the entire flow, including digital loyalty cards, using a modern style and my chosen colours.

• Core Mobile Build
– React Native codebase running smoothly on both iOS and Android.
– Sign-in options: Apple, Google, and email OTP.
– User dashboards showing savings, transaction history, and tier status.

• Subscriptions & Payments
– Integrate either Stripe or Razorpay so users can purchase and manage memberships inside the app. Tier upgrades and renewals should be automated.

• Backend & Future POS Sync
– Develop a scalable Node.js backend with secure APIs.
– Structure the data so it can later sync with the B-MARKET POS system without code rewrites.

Acceptance criteria
• All screens match approved mock-ups and respect the yellow/black scheme.
• App passes App Store & Google Play review guidelines.
• Apple, Google, and email OTP flows are production-ready.
• Test payments complete successfully in both Stripe and Razorpay sandboxes.
• Source code is clean, documented, and delivered via Git.

If you have deep React Native, Node.js, and mobile UI experience, let’s discuss timelines and milestones so we can get this in users’ hands quickly.
