I think the most direct English translation for this word is "finesse". I had only ever known this word as a noun before recently hearing it used as a verb in US prison slang from a documentary.

EDIT: Then again, maybe not. When I hear people in Poland use that word, I'd maybe translate it as "organise" or "arrange", but only in the sense of arranging the acquirement of something.
