Someone needs to check that he's not creating shit at a million LOC per hour. Run some code analysis metrics over his code. Let's say he isn't. Give him these challenges: 1. Increase unit test coverage. When it's at about 85% he can stop. 2. Increase automated acceptance test coverage. And so on. That should buy you time. Then tell him to learn to master refactoring and patterns and let him knock himself out improving code problem areas. That's an endless challenge and he'll get old and tired soon enough.
