Moving to Elixir from Ruby
summary
A Ruby single‑file 937-line single file internal app called Robbie gets rewritten into Phoenix umbrella apps with Ecto and deploys reliably instead of hourly restarts. A monolithic Ruby ETL that took 8 hours to 45 minutes becomes an Elixir/OTP system using supervisors, GenServer workers and a RabbitMQ pipeline with durable queues and AMQP acks so failed jobs get redelivered; some Ruby gems remain invoked via a shell worker while ForceX and ecto_ldap cover common integrations.
