No, don't apologize, you're right. Frontend should be a junior's intro to backend, and I will advocate for this forever. Senior FE devs should be the competent ones who really like FE.
> the FE team has a dedicated QA team
What a headache. Should be unified.
To add to the issues, the FE team has a dedicated QA team, we don’t have any QA for the backend, we just need to do it ourselves. But the QA team doesn’t know what they are even looking at (they’ve never spoken to us). They make sure the UI does UI things, but don’t understand the goal of what it should accomplish, so we (the backend devs) end up needing to do a significant amount of the FE QA, as what they are looking to release is just bad.
