I'm old enough that in a reasonable country I could be considering retirement, and switched into this line of work relatively late. I have no degree, in anything. Each of my jobs was in a different stack so I have no obviously apparent expertise.

A lot of reasons that should be reassuring to most of the rest of you don't worry I'm sure everything will be fine :)

Working in totally different tech stacks should be spun as a superpower. You're a polyglot, not wed to one technology, but can quickly and easily get up-to-speed on the best tool for the job!
