What is a UX Developer and are they really a thing?

Leisa Reichelt, a freelance user experience (UX) consultant based in London, posted a note on Twitter regarding a friend of her who calls himself a UX Developer.

She’s claiming that UX Developer is actually a front end developer with a sensitivity and talent for crafting a UI that is going to be better to use – but in addition to that they have a declared interest in understanding more about the User Experience work that goes ahead of the UI design.
