About the Client

An innovative Canadian locker network provider operating nationwide. The company specializes in automated delivery and pickup solutions and sought to upgrade its customer-facing technology to enhance scalability and reduce the high recurring costs of SMS-based notifications.

Challenge

The client’s existing tech stack relied on SMS messaging for all customer notifications, resulting in significant operational expenses and limited scalability. Without a mobile app, users had no unified interface to manage deliveries or access lockers. The internal development team lacked the capacity to build a secure, high-performance app integrated with legacy backend systems.

Solution

Cross-platform app development

ElifTech built a single React Native application for both iOS and Android, allowing rapid deployment and a consistent experience across platforms.
Legacy system integration

The new app connected seamlessly with the existing .NET backend, ensuring smooth data flow, user authentication, and locker status synchronization.
Modern user experience

A multilingual UI (English and French) was designed for accessibility across Canada. Push notifications replaced costly SMS messages, and users gained real-time access to delivery updates and locker status.
Secure access and scalability

The system introduced secure login, QR-based locker entry, and scalable session management capable of handling rapid expansion into new locker locations.
