You're going to have a ball. Would definitely recommend Germany, once you're there you'll come across plenty of opportunities for sponsorship to other countries of your choosing - just get over there on the Freelance visa to begin with. Or alternatively go to the UK first for a 2 year visa, and find a country that's happy with remote work.

Your biggest hurdle will be your first job in the EU. So make sure your first visa isn't tied to your job, because you'll likely want to change it in the short-term. After that - it's smooth sailing.
