I know most types of computer systems like the back of my hand, at least for my age. I know what happens under the hood sort of speak.
Always been curious about electronics. Got my first phone in grade 1 and rooted it without any fancy GUIs. Hacked into an iPad in grade 4(?). Flashed my first custom ROM into an Android in grade 6(?). Most of my English proficiency even comes from very extensive information searching from grades 1-6, as I was forced to learn English if I ever wanted to learn any of that stuff. Not much information on such topics in Finnish.
Had a quick visit to one of the top universities in Finland 8 years younger than the median age, only to stop my classes there as I saw that I already know 99% of the stuff taught there.
Currently running a business centered around 'data stuff' along with a few other business ventures.
I'm perhaps a bit too proud on certain aspects, but no point in hiding your talents in a forum that allows you to easily create long-lasting relationships with smart like-minded entrepreneurs. If you keep quiet, who knows what kind of relationships you could've developed?
