I understand what you're saying but it's not the case in my specific situation. We're all developers within the same field of expertise and know what we're working with. Some of the code does require clever solutions, but we try to make it as understandable as possible and document the obscure things. This guy however would just disregard all that, implement clever but convoluted solutions to problems and all he would offer as an explanation was "trust me guys, this is how it's done." And that would be all.
