Do you have experience working with message brokers and which ones? At the user level or do you know the internal structure?

I have experience working with several message brokers such as Apache Kafka, RabbitMQ, and ActiveMQ.

At the user level, I configured producers and consumers, designed topic/queue schemas, ensured delivery guarantees, and handled errors.

I am also familiar with the internal architecture of brokers: I understand how message routing is organized, the mechanisms for delivery confirmation, message storage, partitioning (in Kafka), and the specifics of working with transactions and consistency.

For example, in Kafka, the concept of partitions is important for scaling and ordering messages, while in RabbitMQ, routing through exchanges and bindings is key. Knowing these details helps optimize system performance and reliability.
