Been building backend systems for nearly 20 years in Java/Ruby/Elixir. Elixir is by far the most productive language/ecosystem that I've used. I've built 4 systems in the last 5 years and they've all gone smoothly and performed well in production. Only thing on the wish list is full static typing (there's dialyzer which is useful but very much feels like the bolt-on that it is).
