About Me

Hello! I'm a Linux System Administrator, currently working on my own project SkylonHost, a cloud server hosting company. My work consists of managing virtualization environments, security, customer support, network management and various other things.
Outside of work, I enjoy tinkering with various kinds of technology. My interests include embedded microcontrollers, designing electronic circuits and printed circuit boards, exploring the inner workings of the internet and more.
Apart from that, I play the piano and am currently pursuing a degree at a Czech Technical University in Prague.
