He has mentioned in the past that most of his consulting includes non-disclosure agreements. WPEngine is one client that he is allowed to talk about. Also, he prefers not to mention rates because a) they've gone up over time, and b) he doesn't want to have to negotiate against his past self when pricing.
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...
