I remember working with these guys as well all got pulled in to help fix it. Gabe coded in VIM like a like a master violinist. Working with Mikey showed the power of metrics/SRE. Went from having everyone in the room pointing at the next vendor to figuring out part of the bottlenecks. Having a system -- largely broken -- and fixing it without being able to take it off line for major refactoring was like doing surgery on a jogger. What a wild experience.
