Only web dev at work I ever did was in my internship. I have been a backend developer since then. No touching web or front end stuff at all.

That said, to me it sounds reads like you do mention your Web dev experience in either the interviews or the CV. Whenever you mention being bad at it, they hear you are not good at it, which means you are a resource they can throw at it.

Have you tried skipping over and lying about any web experience at all. As if this was something you have no clue about. Like if you mention "don't give me hardware related stuff, I am bad at that" they might hear "oh this guy knows some hardware stuff". So may be treat your FE work like that. Something totally alien to you.

But again, I have no professional web dev experience and my suggestion/understanding could be very out of place.
