I remember running into him at Rails at RailsConf in Phoenix a few years go and brought up his work on the Rails journey router, which is an NFA and his eyes lit up and was really excited that someone appreciated and understood that crucial yet under the hood part of the Rails core. It was enjoyable to talk and meet him.
