Oh, my mistake. I meant: "exact details _for_ what you get paid for" i.e "for what", so I'm not asking exact rates, but more concrete details of the job he has done. And this could be a hypothetical case. So, basically, did he implement some code, or told to implement with very specific details (e.g. at API/types level) to the senior engineers from the client company? Did he work on copywriting or similar? Did he help to determine exact price of the targeting product; etc...
