miracleworker 

Usually said sarcastically about someone who must complete an apparently simple task

All I have to do is teach simple slang words.
Why do I feel like such a miracleworker?

Filthy Miracle Worker 

A friend or confidant that plays Cupid on your behalf. Someone who offers you online dating advice or arranges the opportunity for you to meet new lovers via their Internet profiles.

If the hookup is successful, the person that facilitated the situation is known as a Filthy Miracle Worker.

Dan set me up with a girl he has been talking to on a dating website. Had a great night. The guy is a legend and a filthy miracle worker.
