This could perhaps come off as excessively brutal, but it really is just my true experience in the industry - the worst UIs I have seen (both in terms of UX quality and internal code quality) have been made by that particular kind of developer has has never bothered to go a single inch outside of their little Java/C# box that they were given by their CS undergraduate course, and then, due to some reason like the company doesn't want to hire or move devs around, becomes the senior lead on some big UI piece.
The things I have seen...
Personally, I think that creating great UIs is not something that can be taught overnight. There is a certain kind of "feel for it" that I think that I have gained through my years of making them; something that I feel like cannot be taught, at least not in some "bootcamp"/"crash-course" way.
I definitely agree with this and I think it partly comes down to the fact that product design is always a negotiation between many concerns – all the interface pieces on the view, patterns across views, user expectations, user research, dev LOE, etc. etc. In many ways it's the art of the possible; I say UX is harm reduction b/c there's never a perfect solution for any problem. Work like this is very subjective and always a lot about "feel".
