My name is Krakkus, the author behind this website and the YouTube channel with the same name.
I am 40+ years old and have been employed as a IT specialist for a couple of companies in the past two decades.
As a hobby I have done programming for most of my life in all the major languages including assembly but not java. Done everything from poker-bots to neural networks and 3D graphics when that was still done in CPU.
Now my hobby is partly shifting over into electronics, but I am taking my programmers view on things with me, that helps me a lot.
Both pictures are more than a year old, but still pretty accurate, I like them.
My other two hobbies are sports (running&fitness) and my chickens who run around the house.
