Next to that is a constant overhead of talks with leadership and supporting other engineering efforts throughout the company through things like doc review, chats, pairing, etc.
What he doesn't generally do is "productionize" features - code is generally exploratory in nature or fixes a serious bug (or class of bugs).
I have seen engineers at companies 1/1000 the size of Google generate $4 million in differentiated costs savings (definitely would not have happened without them). It seems plausible to me that someone could generate 10x that at Google.
