Best for

  • Design event-driven microservices communication architecture for order processing systems
  • Implement CQRS with event sourcing for audit-heavy financial transaction systems
  • Select appropriate message broker (Kafka vs RabbitMQ vs SQS) based on throughput and ordering requirements
  • Architect saga patterns for distributed transaction management across payment and inventory services
  • Design idempotency patterns for reliable API operations in eventually consistent systems

What you'll get

  • Detailed architecture diagrams with event flow patterns, message broker selection rationale, and specific implementation guidance for saga orchestration vs choreography
  • Concrete CQRS implementation strategy with event store design, read model projection patterns, and consistency boundary definitions
  • Technology comparison matrix with throughput benchmarks, ordering guarantees analysis, and operational complexity assessment for message broker selection
Not designed for ↓
  • ×Real-time WebSocket implementation or streaming UI updates
  • ×Basic CRUD application architecture without distributed system requirements
  • ×Message queue operational troubleshooting and performance debugging
  • ×Frontend state management or client-side event handling
Expects

Clear description of system requirements including consistency needs, throughput expectations, data flow patterns, and current architecture constraints.

Returns

Detailed architectural recommendations with specific technology choices, implementation patterns, trade-off analysis, and concrete design decisions with justification.
