The Challenge: Enterprise-Scale Mobile, Built to Last
Launching a consumer app for a brand the size of JD Sports isn't just a development task. It's an infrastructure problem, a distribution problem, a compliance problem, and a user experience problem, all at once. The app needed to serve two distinct regional markets (AU and NZ), each with their own App Store and Play Store presence, separate QA and production environments, and independent release controls. It had to integrate with an existing Shopify backend, a headless CMS, a CRM platform, a search provider, analytics, crash reporting, and a customer support SDK. It needed to perform to enterprise standards, protect user privacy across both iOS and Android, and ship without disrupting JD Sports' existing AU/NZ app availability.
UI/UX Design, End to End
Moonward designed the complete app experience for both iOS and Android, from first screen to checkout. Every interaction, layout, and visual decision was crafted to meet JD Sports' global brand standards while being optimised for Australian and New Zealand customers.
App Distribution Architecture
Moonward designed a four-bundle strategy (AU/NZ across Production and QA environments) giving JD Sports independent deployment control per region and per environment. A CI/CD pipeline was built on Bitbucket Pipelines using a matrix strategy across regions, with per-region secrets management and dynamic configuration via `app.config.js`. Expo EAS handled compilation and store submission, distributing builds automatically to TestFlight (iOS) and Google Internal Testing (Android) without credential conflicts during concurrent builds.
Deep Linking and Universal Links
Moonward designed and documented the full deep linking architecture, covering the five-scenario matrix for `apple-app-site-association` and `assetlinks.json` configuration, UTM and query parameter preservation, and edge cases where parameters are lost through deferred deep linking or iOS redirects. The core solution was a centralised deep link handler built to receive links from any source -- push notifications via Bloomreach and CMS-driven content via Contentful (banners, articles, promotions) -- using standard website URLs as the universal link format so the JD content team needs no deep link-specific knowledge. The handler parses navigation parameters (productId, categoryId, promotionId, tracking info), routes users to the correct screen, and handles both cold start and warm start scenarios alongside analytics and tracking. A custom smart banner flow was also designed, detecting whether the app is installed and routing users to the app or App Store accordingly.
Caching and Offline Strategy
Moonward defined a two-tier caching approach: SQLite for persistent core content with TTLs over one hour, and TanStack Query for in-memory user journey data. Low-end Android device considerations were built in, including memory threshold clearing. Offline mode was handled via Expo network connectivity detection, with an in-app banner in the app root and a contextual popup when users attempt network-dependent actions like checkout.
Integration Architecture
Moonward provided technical guidance across the full integration stack: Shopify Storefront GraphQL API, Checkout Kit with native modal, and Customer Account API with Cognito as the identity provider; Contentful for CMS-driven marketing and rich content; Bloomreach for push notifications, CRM segmentation, and React Native SDK integration; Algolia for product search via react-instantsearch-core; Zendesk, where Moonward recommended the Classic SDK over the newer Messaging-only SDK based on the project's support requirements; and Firebase for GA4 analytics, Crashlytics, and Performance Monitoring.
What We Helped Deliver
The JD Sports AU/NZ app was built on a foundation designed for scale from day one. Moonward architected a four-bundle distribution strategy across AU/NZ Production and QA environments, backed by a GitHub Actions CI/CD pipeline that automates delivery to TestFlight and Google Internal Testing without credential conflicts. The technical scope ran deep: Cognito JWT authentication integrated with Shopify's Customer Account API, a two-tier caching model splitting persistent SQLite storage from in-memory TanStack Query data, and a full deep linking architecture covering universal links, UTM preservation, and smart banner routing. Integrations spanned Shopify, Contentful, Bloomreach, Algolia, Zendesk, and Firebase, all built to defined performance standards: sub-2-second cold starts, 55+ FPS, and a crash-free rate above 99%.
project team
Delivering this required more than technical skill. It took a team that could move fluidly between UI/UX design and infrastructure decisions, and hold both to the same standard. Moonward designed the complete app experience end to end, from first screen to checkout, while advising on release governance that let JD Sports catch issues before they ever reached users. That same team navigated low-end Android constraints, offline mode design, and platform-specific edge cases like deferred deep linking, always with an eye on how the technical choice would land for the person holding the phone.
Forever Forward
The JD Sports AU/NZ app launch is the kind of project that tests the full range of what a software team can do. It demanded deep technical architecture, precise coordination across two regional markets and two platforms, expert integration across a stack of enterprise-grade tools, and an end-to-end design that held up to one of retail's most recognisable brands. Moonward delivered all of it, built for scale and designed for people.
