Sound familiar?
- Inventory drifts between your store, marketplaces, and ERP.
- Pages are slow and conversion suffers.
- Promos and sale days expose fragile code.
- Your agency's backlog means changes take weeks.

Common questions
Will this turn into a sales pitch?
No. The call is about your project: what needs building, what's stuck, and whether we have the right engineers. If we're not a fit, we'll say so.
What do I get for free?
A project plan, roadmap, cost estimate and ROI estimate within 48 hours of your project call. Your first 5 development hours are free, too. We agree the scope and any paid work with you before proceeding.
Do I need a spec or brief?
No. Tell us the problem in plain words and we'll help shape the scope with you.
Are the engineers really in the U.S.?
Yes. Every engineer lives and works in the United States. No offshore hand-offs, and that's in the contract.

Hire US-based React Native developers for iOS and Android shopping apps with product browsing, saved carts, checkout, and order tracking. Mobile commerce introduces problems beyond a responsive storefront: deep links must open the right variant, payment authentication can interrupt app sessions, and weak connections can leave shoppers unsure whether an order succeeded. Plan these behaviors alongside your Shopify Storefront API or custom commerce integration.
Your NextGen Coding Company engineer works from the US, shares your working hours, and joins team standups. Set the technical brief around Expo or your native build setup, payment SDK compatibility, and catalog caching rather than screen count alone. We sign an NDA and full IP assignment before development begins. Book a 15-minute call to discuss the shopping journey and engineering requirements.
Frequently asked questions
- Can a React Native shopping app connect to Shopify?
- A React Native app can use Shopify's Storefront API for product discovery and cart operations, with checkout integration chosen around Shopify's supported mobile flow. Keep administrative credentials out of the app bundle. Plan customer authentication separately, and test product availability, checkout return links, and order confirmation across both iOS and Android.
- How do React Native apps support Apple Pay and Google Pay?
- For eligible physical-goods checkout flows, payment providers such as Stripe offer React Native SDKs with Apple Pay and Google Pay support. Configuration involves platform capabilities, merchant setup, and server-created payment sessions. Digital goods may require different store billing flows. Confirm the product category and current platform requirements before selecting the payment implementation.
- How can we prevent duplicate orders after a mobile payment retry?
- Treat order creation and payment confirmation as server-owned operations, using idempotency keys where supported. The app should restore checkout status after backgrounding, authentication redirects, or a lost connection instead of blindly repeating a request. Test delayed webhooks and repeated button taps. A disabled purchase button alone does not prevent duplicate processing.
- How do we keep large React Native product catalogs responsive?
- Use paginated queries, appropriately sized images, and virtualized lists such as FlatList or FlashList rather than rendering an entire catalog. Profile on representative lower-powered devices, not only recent simulators. TanStack Query can manage cached catalog responses, but prices and availability need revalidation. Separate browsing responsiveness from the backend's search and inventory latency.
- What should a React Native ecommerce developer know about deep links?
- They should understand iOS Universal Links, Android App Links, and navigation state restoration. Product links need reliable handling when the app is closed, already open, or awaiting sign-in. Checkout return links require particular care so the interface verifies order status with the backend. Test unavailable products and malformed parameters alongside successful campaign links.
- Are your developers really based in the US?
- Yes. Every engineer lives and works in the United States. No offshore subcontracting and no hand-offs to another team. That's written into the contract.
- How fast can someone start?
- Most teams interview matched engineers within a week of the first call. Start dates depend on your interview process.
