Or, you just think you’re literally that person. No offence, I’ve met my fair share of developers who are full of themselves but are barely tolerable at best.
Well they didn’t say that they are specialist level at both. It could be that they are mid/good level at both, which isn’t a particularly egotistical view to have of oneself. I got the impression that they were highlighting their skillset is more broad than deep, which is basically what you’d expect from a good full-stack developer.
I’ve met a lot of programmers early in my career who were full of themselves, and a number of more experienced ones later in my career that understood their own capabilities very well.
