Hello and welcome,
You might have a look at…
It is not about microservice, but chat application.
For CQRS/ES You might get some inspiration from…
GitHub - commanded/commanded: Use Commanded to build Elixir CQRS/ES applications.
BTW It’s possible to use microservice architecture, because the BEAM use message passing between lightweight processes. At a macro level, it’s possible to distribute between nodes.
You can go very far with Elixir only. But switching mental model is complicate,
