A couple issues I have with this in particular:

> "Increased revenue by $18.7M by reducing time-to-first-interaction latency from 2.3s to 117ms, increasing conversion by 47% and LTV by 28%,"

The first is that they're playing fast and loose with their numbers. Latency has before/after, conversion and LTV have percentages; revenue is just a single number. Did that double revenue? Or is that half a percent, and is it lost in the statistical noise?

The other is that there's nothing there to convince me that the technical work was was the full cause, instead of, say a new marketing promotion that launched at the same time, or another team redesigning the landing page flow, or another team re-doing all the product photography, or any other concurrent work.

Maybe all those questions have good answers, but I would at least want some nod in there to how they validated it. I find people who focus on "business impact" but don't know how to do the math to have confidence in it dangerous, because it's so easy to cherry-pick numbers that will make execs happy at a glance and prioritize for those things instead of actual long-term system or product or customer-facing improvements.

I'm not binning the resume for it, and maybe it helps get past the people who see it before I do, but I'm gonna dig in on it. And I'm usually disappointed by the answers.
