The Challenges We Faced Along the Way

Building a next-generation loyalty and engagement app for a leading UK retailer presented several challenges that required innovative thinking and precise engineering:

Dynamic UI Updates without Redeploying

The client needed the ability to change app layouts, banners, and content dynamically without pushing updates through the app store.

Secure Account Handling

Supporting both social and traditional login methods while maintaining robust security for sensitive user data and payment information.

Real-Time Live Chat Integration

Integrating a seamless real-time live chat experience within the app to provide instant customer support without third-party dependencies.

QR Code Integration

Implementing QR code scanning functionality for in-store loyalty card usage and promotional offers.

Content Flexibility

Enabling content updates and UI changes without requiring app store submissions, reducing time-to-market for campaigns.

Our Primary Approach for This Project

Brainium adopted a cloud-first, modular approach to ensure the app was scalable, secure, and future-proof. Our technical and design strategy focused on:

Apollo GraphQL for Dynamic UI

We leveraged Apollo GraphQL to power dynamic UI rendering, allowing the client to modify app layouts and content without redeploying to the app store.

AWS Connect for Live Chat

We integrated AWS Connect to deliver real-time live chat support directly within the app, ensuring customers get instant assistance.

Native iOS Features

Built with Swift, we utilized native iOS capabilities for QR code scanning, personalization, and smooth user experience.

Cloud-First Scalable Infrastructure

The entire backend was built on AWS services including S3, DynamoDB, and Connect, ensuring high availability and seamless scalability.
