Industrial automation, mostly for underground coal mines. I have an app that connects to SCADA for reporting, reads machine data for replaying machine operation, and various other things. It is mostly Elixir, with a bit of F# and C# where it is needed.

Industrial automation for hydro electric production. Elixir/Phoenix is used to get data from automata on remote sites (producing electricity from turbines), send commands to them, automate some actions, produce various alerts, store/query data in PostgreSQL (almost no Ecto, I love SQL),… The system was rewritten multiple times over the years and now is stablized since a few years on Elixir (and Phoenix) and PostgreSQL. Best move ever. The last rewrite was from Erlang to Elixir I love FP, Erlang, Elixir, OTP, the process idea, i.e. the whole philosophy, and… Phoenix LiveView. This is dope. The community is fantastic, the ressources are great, the friendship between Erlang and Elixir is astounding. I it. There are also some scripts in Ruby and Java also but I tend to write the new ones in Elixir.

When it comes to processes, threads, inter-communication, distribution, … my feeling is that nothing can beat Elixir (and Erlang of course).

I work at a consultancy, envylabs.com. I built and continue to work on a client app written in Elixir, gamedaymath.com, which is in the sports betting industry and primarily provides analysis of offered betting lines to sports bettors.
