+1 I've only had incredible experiences with Ukrainian devs and designers- I hesitate to say best because I've worked with amazing people all over (I was at two gig economy companies that did custom software dev with freelancers) but Ukraine as a destination often stood out for high quality, low prices, and not needing a ton of supervision/detailed instruction.

Shameless plug- a buddy runs a dev shop out there, they have great devs and exceptional designers (and also are doing a fund for Ukrainians impacted by the war). If you're looking for help in that region, they're great people to chat with: https://beetroot.co/
