I like to measure things. In real life and on computers. But I also have a couple of work reasons for it:

As a remote worker, I'm under extra pressure to prove that remoteness works.

As a senior employee, I'm also under pressure to regularly report where my time is spent.

At big tech you have to quantify your value like this regularly, so yeah everyone keeps track of the minutiae.

If you look at many of his recent blog entries, it is clear he has felt the need to quantify his impact to prove he isn’t less effective as a remote employee in Australia working for a company in the US.

Use gcalcli to search for meetings with customer invited. That's it! Also, for an engineer that isn't in sales, 110 customer meetings is A LOT.

Of course, always take notes, they will help when doing escalations, or justify oneself in review meetings.

Parse your calendar export (.ics) file and count events of a certain name and voila?

Isn't that show-off? I mean you have achieved is good but feels like bragging about it ! Just a thought

A lot of people consider score keeping like this to be more important than the job itself.

I can't even say that they are wrong.

I mean maybe. We often have weekly customer meetings. One of my programs has 2 customers, we meet with both weekly. So do I put idk 200+ customer meetings? That seems like a weird metric because it's like "compiled code 400 times." I've seen resumes that have the same vibe. We did not hire them. Sometimes it's very telling what people think are accomplishments.

All startups in due course turn into Byzantine labyrinths of bureaucracy. Only the record keepers survive.

"Count your meetings"

Wouldn't hurt to try!

The fact that they were busy keeping count during those 110 occasions and for every other activity clearly tells that they nothing better to do. You have to be loud about such numbers when you have very little meaningful work to show for.
