Skills

Reactive Systems has specialised in the development of web-based business applications. We create backends in C# using the Microsoft .NET Framework as Services or APIs. They usually run in the cloud and the local intranet. The frontends are being developed in JavaScript, HTML and CSS with Angular and can be used by browser-enabled systems. If required, we can also develop WPF frontends and dock them to the backend.
