Often in a professional setting, I want to say "X has really been kicking ass (and taking names!)"
Sometimes I say "kicking butt" but it doesn't have quite the same emphasis. I don't want to say ass as I don't think its polite in some contexts. What is a equivalent expression that is polite yet just as encouraging?
In accordance with the comment suggestions, I will clarify that this question is asking about "kicking ass" in the form of doing really well, not necessarily beating someone else in a competitive sense - to trounce, cream, take them to the cleaners, etc. If Sarah is kicking ass at real estate sales, she's not necessarily beating anyone else, just doing really well.
