There's lots of code that puts data in databases and gets data out of databases. That code is usually intimately involved with the database schema. I suspect that you could get a job doing that without having to go back to junior salaries... but not necessarily at your current company.

You also might not be able to do it in JavaScript. You might have to use Java or C#.

You might look around at your current situation. Identify the people who write code that interacts with your databases. Ask their manager/lead (and your own) if you can, part time, work with that team, or if you can transition to working on it full time.
