Welcome from some one who likes technology, and sincerely think and hope, that we can solve a lot of the worlds problem by technology and innovation.
In my everyday life I work with SCADA and DATA systems from Wonderware and OSI-Soft, which are used to control and collect data from some of the largest wind turbine generator farms in the world. Among others, London Array and Horns Rev 2.
In my sparetime I like to learn new technologies, which so far has materialised in an Android App, which is used by farmers. I am learning Objective-C (More Swift now actually) at the moment, as I like iOS much better than Android. It is just such a more mature platform.
