I can’t be the only person who thinks “full stack” translates to “master of nothing.” One of the best career moves I ever made was shrug off the pressure to go full stack, and dedicate myself to backend only.

I think knowing about frontend is important for a senior or higher level engineer. I would expect someone at that level to be able to contribute where necessary, and know enough to make sane decisions and know when those decisions impact backend/frontend. But to be equally good at both isn’t reasonable
