Well, I don't think there's necessarily anything "wrong" with it (It's actually from my own resume), I just cringe when I read it. It reminds me that I operate within a world obsessed with jargon and eye-roll inducing business speak. It all feels so unnatural to me.
When I see things like that on a resume I instinctively smell bullshit. Right or wrong, that's my reaction. "Proven?" Show me the proof. "High-quality and performant?" I better not be able to quickly and easily find end users complaining about your companies software.
There's so much suspicion in this industry. Is it so in other industries? We see a 20 year work history, and we assume you must be lying so we LeetCode you in front of a couple recent college grads. And now we're going to go after end user complaints as well?
I guess its good I work on the back end, I can always blame poor user experience on the front end and "UX" people.
I'm suspicious of people that need to dress up their 20 years of experience with business speak, yes. It is the business speak specifically that makes me suspicious.
Everyone does this because everyone thinks they need to. So you're suspicious of everyone, but the only thing you can legitimately suspect is that they're the kind of person that does what needs to be done.
