>Is there a hard ceiling for salaries for developers?
Yeah I think there is a limit to what the market will pay for any particular skill, including developers. That limit will be constantly in flux year-to-year (see the 2017 results for comparison), and will vary from person-to-person though as skills, experience, etc. vary. Hard to quantify what that cap might be for any specific person, but looking at all the data in aggregate you can see that salary growth isn't linear with experience.
