Before brexit I was considering UK. I'd heard that speaking English is OK for work in many other countries. No problem to learn another language later.
I had a nice offer for Vienna two years ago but I refused after strong family protests. Now the situation is different for a few reasons so, starting August, I'll be looking again.
It's incredible how different are salaries just crossing the border. One would believe that sharing a common currency that wouldn't be the case, but we earn half the money for the same positions. And not only developers, just any profession.
<sigh>
Where is it?
