troubleshooter

A troubleshooter is a person who fixes things or solves problems after zeroing in on their sources. When your car refuses to start, you may need to pay a mechanic to act as a troubleshooter.

Computer experts often act as troubleshooters for big companies, diagnosing and repairing any trouble that arises in the computer network. Editors can be troubleshooters for filmmakers, deleting extra scenes and combining others in ways that solve problems with the narrative. In either case, troubleshooters deal with problems. The original troubleshooter, from the 1890's, was a telegraph or telephone line repairman.
