Been a web dev for 20 years.

Yes, but work on learning the full stack. Learn frontend, backend, SQL, sysop. Can you set up a server from a base image and eventually have a full app running reading from a database? Great! Now get familiar with cloud solutions like AWS. That might sound daunting, but it's actually easier in some respects. You don't have to know everything before you get a job, but knowing a little of all will show great promise in an interview.

Don't get attached to any one technology or programming language. This field changes all the time (annoyingly so). There was NOSQL, React, Node, hell I remember the times before Memcache. So keep your eyes and brain open and be ready to adapt. Your current place of work will likely stay stale with whatever they have, but if you don't keep up with the outside world, finding your next job will be much harder.
