I'm interested in many aspects of software and hardware.
My preferred programming language is java since this is what I started with back in 2014/2015. But I'm also into basic Web-Development, Arduino, VBA, R and more.
On the hardware side I'm maintaining my own infrastructure including a private Unraid-Server for hosting VMs and as a NAS. I'm also building my own smart home gear where no commercialy available products can be found or are just unfeasible to buy.
