inteligy is an owner-operated energy supplier and digital process provider for the housing industry based in Cologne and operating since 2013.
We were responsible for the planning, design and implementation of the software architecture/systems for inteligy's digital processes. The following processes were implemented as web, mobile app or as API:
- Automated reading of electricity, water and gas meters via mobile app for Android and iOS
- Heating costs with the HeatHub as a web application
- Digital workflows e.g. Accommodation provider certificate
- Customer portal
For a consistent coperate identity between all inteligy web applications we developed a design system. The design system is based on Angular Components and Tailwind CSS.
In addition, users should be able to switch between the individual web applications easily and quickly, using the same user data. To enable the integration of the web applications, Keycloak was used as a single sign on system. The permissions for the web applications were controlled via Keycloak and logged in users could easily switch between authorized web applications.
