If you are using a service (firebase) then you are a customer or end-user, not an administrator, and a full-stack is somebody that is a developer and an administrator at the same time.
However, I am not saying that you can't build a full system using a ready-made service.

Yeah most probably firebase users are beginners or novice devs.
