I couldn’t imagine tying myself to a single category for my whole career.

I’ve done front end, back end, database, web, Windows, and Linux development. If the job calls for learning something new, I’m on it. These days I’m making datacenter software for admins to use to manage their distributed applications. Before this, I was doing the same thing for factory automation at the edge.

Specializing has its value, but the more flexible you can be, the more useful you will be when the landscape changes and your boss suddenly asks you to set up an AI system or something.
