Answer

I agree with Hasan - the nuts and bolts guy handles things on a practical level.

By the way, "slang" is an uncountable noun, and never made plural: "and a lot of slang bothered me."

Answer

I guess it means a guy who knows A-Z of how things are done PRACTICALLY (not theoratically) in that particular company.
