What is the salary bracket for Salesforce Developer with 7 yrs of experience?

What do you know about Salesforce Development? Judging by your comment I don't think anything.

I know Salesforce is a CRM like tool & a bit much more. But I believe that any resourceful developer would be able to make API calls to it and get up to speed with it just like how they’d pickup react or angular today and spring boot tomorrow. There might be some gotchas here and there, this is where a Salesforce certified developer would be required and maybe their efficiency would be higher than a back end dev.

That’s my opinion, but I’m happy to be corrected as we all learn something new everyday.
