This is dubious. I see a lot of "I'm doing the same as him/her/that level but only getting paid x" and it's often not true. Either in terms of responsibility or expectations (for example nobody really thinks an offshore / outsource provider will deliver the same as in-house) you are probably doing less. The solution is to get the job you are comparing yours to.
There where times in my life when I thought I was hot shit. And if you only looked at Jira and git, I WAS good, but I was also green and lacked a lot of knowledge and wisdom compared to more experienced coworkers who I assume got paid more.

Edit: this comment posted at the same time as mine is saying exactly the same from an employer's perspective: https://news.ycombinator.com/item?id=32718612
