In cooperation with the renowned concrete5 developer John Liddiard (aka JohntheFish), we have developed an intranet application for the management of potential advertising locations for the German outdoor advertising industry. With this web-based application, it is easy for the user of the application to keep an overview of all open processes. Projects, contacts, and reminders / activities with attachments can be created. The customer's requirement was to implement extensive administration and permissions for user groups. For this purpose, we build on the core functionalities of concrete5. Aside from further features such as logging and an online image editor for photomontages, we have also implemented a message system that automatically notifies the user via e-mail, as well as sends an internal message as soon as a task has been assigned. The project has been developed multilingual, is absolutely state-of-the-art, of course 100% responsive and has been implemented with great care and loving attention to detail.
