RabbitMQ

Uses RabbitMQ with MassTransit/EasyNetQ in .NET applications at a basic level. Publishes and consumes simple messages following established patterns. Understands exchange types, queues, and basic routing concepts.

Uses RabbitMQ at a basic level. Performs simple tasks using established templates. Understands basic concepts and follows team practices.

Works with RabbitMQ via Spring AMQP: sends messages to exchange, listens to queues via @RabbitListener. Understands exchange types (direct, topic, fanout). Handles errors through retry and DLQ.

Independently implements RabbitMQ messaging with MassTransit in .NET: sagas, consumers, retry policies. Configures dead-letter exchanges and priority queues. Writes integration tests with TestHarness for message-driven workflows.

Independently implements RabbitMQ messaging in Elixir with Broadway/AMQP library. Leverages OTP supervision trees for consumer fault tolerance. Configures prefetch counts and acknowledgment strategies for reliable processing.

Designs RabbitMQ topology for Java services: exchange-queue bindings, routing keys, priority queues. Configures publisher confirms and consumer acknowledgment. Implements retry with exponential backoff. Monitors via Management Plugin.

Designs RabbitMQ-based messaging architecture for .NET microservices with MassTransit. Implements saga orchestration, outbox pattern for reliable messaging, and federation for multi-datacenter setups. Optimizes throughput with batch publishing and consumer scaling.

Designs RabbitMQ messaging architecture for Elixir/OTP systems. Implements custom Broadway producers with backpressure, shovel/federation for cluster bridging. Optimizes consumer concurrency leveraging BEAM scheduler capabilities.

Designs reliable messaging architecture: federation for geo-distributed systems, shovel for cross-cluster replication, quorum queues for consistency. Optimizes throughput and ensures message ordering.

Defines RabbitMQ architectural standards for .NET platform. Establishes messaging conventions, topology management practices, and monitoring dashboards. Conducts design reviews for event-driven architecture with MassTransit patterns.

Defines architectural decisions for RabbitMQ at product level. Establishes standards. Conducts design reviews and defines technical roadmap.

Defines product messaging strategy: choosing between RabbitMQ and Kafka, message format standards, routing conventions. Implements monitoring and alerting for queues.

Defines enterprise messaging strategy evaluating RabbitMQ vs alternatives (Azure Service Bus, Kafka). Shapes company-wide event-driven architecture standards and reference implementations. Establishes messaging governance and migration roadmaps.

Defines RabbitMQ strategy at company level. Evaluates new technologies and approaches. Establishes enterprise standards and reference architectures.

Designs organizational messaging platform: multi-protocol broker, integration patterns, event-driven communication standards across domains. Defines SLA for message delivery.
