Client Overview

Collecto provides night-taxi services in Brussels, serving thousands of users monthly. The service required a modern, reliable mobile application to support their growing customer base.

Challenge

The original Collecto app, designed to let users order shared taxis from any STIB (Brussels public transport) stop, suffered from an outdated interface, limited features, and poor user feedback—reflected in its 2-star rating. With a tight deadline of two weeks, Taxi Verts needed a complete overhaul to improve usability, integrate payments, and restore public trust in this innovative mobility service.

Solution

We reimagined the Collecto app from scratch, delivering a sleek, user-centric experience in record time:

• Revamped the app using React Native with Expo for a modern, cross-platform UI/UX, accelerated by EAS for rapid build and deployment cycles.

• Integrated in-app payments via Adyen, ensuring secure and seamless transactions.

• Powered the backend with NestJS, providing a robust, scalable foundation for real-time operations.

Working closely with Taxi Verts and leveraging agile development, we met the aggressive two-week deadline without compromising quality.
