Hi, In my opinion its all depends on your German language skills & Your expectation in coming few months/years. Poland is not far. you can be present here for job interviews (which I think suites to employers). Berlin, Munich & Frankfurt could be good start.
Visit Monster.de or find some local job agencies in Berlin. then you can assess your situation better.
But once again. Language is key :)
Good luck
