I'm putting more time into cleaning up my LinkedIn profile since that's been my most reliable route into hiring pipelines (other than referrals and networking).
This is the "quantify everything" mantra career coaches have been repeating for decades. As the story goes, no company is going to care that you refactored the FooBar library in order to make bugs in the DingDang module easier to fix. You have to only write down things that moved some quantifiable business needle like revenue or signups, even if the link to that needle is tenuous. Obviously, this ends up penalizing hard working, talented devs who don't happen to be working in areas where wins are easily quantifiable.
It's the useless quantification that turns resumes into noise, combined with making claims that you changed revenue by yourself.

Every hiring manager knows this game and sees right through it. You can't read 1000 resumes with claims of "Increased revenue by 13% by" followed by something that clearly was not the reason revenue increased 13% to become numb to it.
Nobody believes these.
The somewhat useful quantifications are things like "Reduced cloud spend by 50% by implementing caching". This can spark a conversation about how they diagnosed they issue, made a transition plan, ensured it was working, and all of the other things we want to hear about.
This is a person who you're going to be reviewing their code or reading the documentation that they write.
If there are typos and poor formatting in the resume (that they've had the leisure of reviewing themselves and correcting), what does this say about the quality of the code the code or documentation that they're going to write when under a time constraint?
Are you going to be faced with the decision of having code with variables that have spelling errors and documentation that is grammatically or factually incorrect go through because of the time pressure?
The resume itself is a demonstration of the applicant's ability to pay attention to the details that matter in software development without showing a single line of NDAed code.
