I replaced that guy at my company (similar size) and a year in I'm barely scratching the surface of the horror, a lot of the time I end up putting a safe interface in front of it and a big note saying fix this at some point. It's nor even that the code is bad (and it is) it's that he couldn't think straight, the business logic is all insane as well. Still boss hired me to sort it out and the time scale is measured in years (week is a mix of new stuff and fixing old stuff). Typical performance improvement is two orders of magnitude. When I started it took 70s to search for a quote. Now it takes 200ms and mine includes the line details on the quote in a easy to eyeball format. My boss seems happy at least.
