Best for

  • Design event sourcing architecture for complex business domains with audit trails
  • Implement CQRS read models and projection strategies for high-scale query workloads
  • Plan aggregate boundaries and event schema evolution for domain-driven systems
  • Architect saga patterns and process managers for distributed business workflows
  • Select and configure event stores (EventStoreDB, Kafka, PostgreSQL) for production systems

What you'll get

  • Complete aggregate design with command handlers, event definitions, and invariant enforcement logic
  • Event schema specifications with versioning strategy and upcasting patterns for backward compatibility
  • Infrastructure architecture diagram showing event store, read model databases, and projection rebuild strategies
Not designed for ↓
  • ×Simple CRUD applications where event sourcing adds unnecessary complexity
  • ×Real-time analytics or streaming processing outside of business domain events
  • ×Message queuing or pub/sub systems that aren't domain event-driven
  • ×Traditional database design or relational modeling patterns
Expects

Business domain context, consistency requirements, audit needs, team experience level, and specific technical constraints or performance requirements.

Returns

Detailed event sourcing architecture with aggregate design, event schemas, read model strategies, infrastructure recommendations, and operational patterns.
