Hi, my name is Derek Nutile and I make web stuff.
I first saw the Netflix cheat codes on Reddit and the source sauce here: https://medium.com/@unblock.com/netflix-cheat-codes-the-open-sesame-of-entertainment-7fb0b75a847f#.ml0xm1kx5. A student at George Washington University named Ben Shepard built a similar category search at http://netflixcodes.me/.
I had already built a filter for FontAwesome at http://fadbus.github.io/, so I stole my own code and made the Netflix Cheatcodes filter you're looking at today. I added some meta data to help the filter find categories easier. Why don't you check out the open source project or hit me up on Twitter?
