Techni-ho

technical whore. Professional contractor or service provider in the public or private sector who sells their technical expertise for money. This is opposed to a "techni-slut", who gives it away: a consultant, expert witness, a contract employee

Joe was torn between continuing as a techni-ho, the money he got consulting was good, but the lack of security and benefits made him uncertain; the alternative of "going native" and marrying the company would mean learning to play by others rules.
