Yeah, that must have been my collegue. Usually he was in charge of implementing all the new stuff, because he was able to deliver fast. And then I had to refactor, or usually just rewrite and redesign the whole thing, because it was immediatelly unmaintenable. I didn't mind, since at the end of the day, he was really good and doing these prototypes and selling them to management. I was good at making the application last and stable, so it kinda worked out.
