Why not say something like "I make computers go harder, better, faster, stronger?" Funny, doesn't make you sound like you're apologizing for what you do, and if someone's really interested ("how does that work?") you can follow up with an explanation. I'd try for some metaphors, too, like "Servers/computers are always juggling tasks, and what I do gives them more arms to juggle with."
I know your last question was rhetorical but if you start doing something that makes you unhappy just to find a partner then you will have a partner who loves you when you're unhappy. Not a great idea.
