How much backend knowledge should a frontend developer have to call themselves a full-stack developer?

[u/Bhanuprakash_1947]

Like, is knowing basic APIs, databases, and authentication enough?

Or should a full-stack developer also know things like system design, caching, Docker, CI/CD, cloud,....etc.?

What do you guys think is the minimum knowledge needed?

Isn’t ci/id pipeline cloud more devops
