Cross Platform Shopify Purchase App

I run a Shopify-based store and I’m ready to give my customers a seamless mobile shopping experience. I need a developer who can create a native-feeling app for both iOS and Android that connects to my existing Shopify catalogue and lets shoppers move effortlessly from product pages to a secure checkout.

The core job is straightforward: customers must be able to select items, add them to a cart, and complete their purchase without ever leaving the app. All inventory, pricing, discounts and payment methods should stay perfectly in sync with Shopify through the Storefront API and Webhooks.

Beyond the purchase flow, I want the app to feel alive and engaging. Each product page should surface our existing customer reviews, and I’d like push notifications set up so I can send promotions, order-status updates and abandoned-cart reminders. Please match the look and feel of my current theme while optimising for mobile speed and usability.

I’m open to React Native or Flutter—whichever will deliver smooth cross-platform performance and allow easy maintenance. Secure payment integration (Apple Pay, Google Pay and Shopify’s checkout) is non-negotiable, and the code must be clean, well-documented and committed to a private Git repo.

Deliverables
• Production-ready iOS and Android builds, signed and ready for App Store / Google Play submission
• Complete source code with build instructions
• Brief documentation on setup, key APIs and how to trigger push campaigns

Acceptance criteria: the app passes App Store review, processes a test order end-to-end, and receives a push notification on both platforms.
