Here's another Alexa-Kodi project that's very similar to what you are doing.

I installed this one as well as yours. This one has the advantage of not requiring Heroku. It did work well for me. The features he mentioned like searching Netflix and Pulsar won't work on the Fire TV, but likely work well on some other platforms. He requires chrome launcher in order to call Netflix and that's not calling Chrome properly on FireTV.
