For those who are not aware, Jose Valim (the creator of Elixir) live-streamed all his solutions to this years Advent of Code on Twitch (found here: https://www.twitch.tv/videos/346878345?collection=YDM6eKu6bh...). I found this to be very informative and enjoyable. It is definitely worth checking out regardless of your proficiency in Elixir.
