Core Platform Enhancement for European Car Park Booking Company


Onepark is a France-based mobile app and online car park booking platform that lets customers compare, book and pay for the parking space at more than 2000 car parks, in 275 cities throughout Europe. The app provides travelers with access to public car parks as well as private lots belonging to hotels, companies and buildings, thus making a wider number of parking spaces available.

Business Challenge

The company was founded in 2014 and has grown rapidly since then.

While Onepark expanded into new business areas and markets, their existing application became expensive in support, and the company’s maintenance costs grew significantly.

Moreover, to accelerate its growth in Europe the client needed a new point of sale and customer service platform. Onepark selected DataArt as a technology partner that could upgrade their legacy system and build a modern mobile application.


The solution design phase allowed to revise the client’s technological landscape, as well as the business process.

The implementation started by migrating the monolithic application written on Ruby onto Micro-Services Architecture, leveraging node.js and React Native technologies.

Apart from that, DataArt built an API layer that became the groundwork of the new Onepark platform and a new mobile application for iOS and Android.


DataArt helped Onepark to enhance their legacy system to ensure easier maintenance while increasing flexibility.
