My focus is the development of embedded microcontrollers. Currently I'm using ESP32 wifi microcontrollers, to integrate various devices with HomeKit. For now I'm able to open the garage with HomeKit. Future/current projects are the intelligent controlling of the heater and lights with various sensors or generally the intelligent integration of all devices.
In the past I haved work on the development of iOS and macOS apps, which I have also released in the App Store. On the one hand the iOS app MPDPlayer, which is used to control any MPD-Server and at the other hand the macOS app LUT Viewer, which is used by photographers and graphic designers to apply LUTs to images or videos.
