Oh man, I see so many resumes littered with these kinds of statements. I totally gloss over them as they generally read like BS, and are formulaic enough that they just represent another "how to sell yourself" job-hunting checkbox point. Lots of devs would love to have some way to quantify our impact in monetary terms but the reality is that "process/tooling change X -> $Y ARR" is basically always hand-wavy made up math.
