Do we use does with someone?

Excuse me, but I'm a bit confused about the usage of "does" in this context. Are you suggesting that we use "does" when referring to someone, in the sense of asking about their actions or characteristics? For instance, would we say "Does she like coffee?" or "Does he work in finance?" Could you clarify your meaning and perhaps provide a few more examples to help me understand the proper usage of "does" when addressing someone specifically? Thank you.
