Building a tool for business

The web application functions as the main tool of communication between colleagues, as well as for internal company information for thousands of users on a daily basis.

Being responsible for a system that large puts high demands on the system to be both reliable as well as being easy to branch and support.

Apart from being reliable, the system also needs to be very accessible on all platforms and devices. The web application (as well as the Challengera company website) is fully responsive so that users can participate in discussions and activities on the web app via their mobiles and tablets while on the run.

Apart from design and front-end, Red Onion also created the application’s vast backend systems. The application comes packed with customized features to cater to the needs of both Challengera staff, client managers and their employees.

Customizable emails, file libraries, news articles, private messaging, detailed statistics charts and reports are just some of the features and functionalities we have created for the application.
