fachidiot 

Essentially an idiot savant. A one-track specialist who is an expert in his field, but takes a blinkered approach to multi-faceted problems.

Justin is an ingenious poker player but he is a fachidiot, or, a narrow minded idiot, who thinks he’s a genius at all facets of life and knowledge but usually just ends up annoying and offending others.
