Rabbitmq Expert

This is a proper RabbitMQ engineering skill that leads with TDD and production reliability patterns. You get concrete test fixtures for both unit and integration testing, proper ack/nack handling with dead letter exchange setup, and prefetch tuning examples. The core principles are solid: durability, publisher confirms, observable queue depths, and designing for failure from the start. Most RabbitMQ tutorials skip the testing piece entirely or handwave production concerns, but this one shows you how to verify message flows work before you ship them. Worth using when you're setting up message queues beyond trivial demos and need patterns that actually survive production.
