Instead of ranting I thought it would be nicer to ask for opinions/solutions: How to cope with a collegue that keeps producing trainwrecks of code which you have to first refactor to make it work in a more logical/structured way? Yes, his initial solution works (in a way), but it's just not how 99% of the other developers would solve it. And yes, we've shown him quite a few times how it should/could be (in a positive and constructing manner)
