Not to pick on you specifically, but "Europe" is a pretty big place. The countries are all quite different from one another with different requirements and attitudes, etc. Your best bet, in my opinion, as someone from the States who lives and works in Spain and has no formal CS education -- save up, research the country you like, go there on a Schengen visa, find jobs and interview in person and stay there. You got 90 days on a Schengen visa. If you have experience in your field, you can find a job. That's how you get it done.
