Digital coupons, barcode and weekly flyer in one retail app for PENNY shoppers
We delivered a retail app for PENNY with exclusive coupons, customer accounts, a digital barcode, a smart shopping list and the weekly flyer, built on TypeScript, Vue.js and Google Firebase.
The Challenge
PENNY wanted a retail app that makes shopping more convenient for its customers. Coupons, the weekly flyer and shopping lists needed to be available on the phone, tied to a personal customer account. The app had to sync data in real time and stay reliable as it grew.
The Approach
We built the codebase in TypeScript, with Vue.js for the interfaces. Google Firebase provides the infrastructure: Authentication for customer accounts, Cloud Storage and Cloud Functions. We covered the code with automated tests in Mocha. The app's features: exclusive coupons, personalized customer accounts, a digital barcode system, a smart shopping list and a digital weekly flyer.
The Results
The app delivers a fast, responsive interface with real-time data synchronization. Customers get exclusive coupons, a digital barcode and their shopping list in one place, linked to their own account. PENNY customers can now use coupons, check the weekly flyer and plan their shopping from their phone.
