They rewrote the whole back of house system from Java to elixir and apparently it’s been a huge success.
I tried to look around, but is there a blog or something detailing before/after/why etc.? Should be very interesting read..
One of them gave an elixir conf talk about how they built an elixir team[1] and this one from 2022 which isn't online yet[2]. I know a little more about it from talking to them, but couldn't accurately describe the transition from memory.
