CQRS & Event Sourcing Architect
Design and implement CQRS and Event Sourcing architectures with proper aggregate design, event schema evolution, projection patterns, and consistency guarantees grounded in Domain-Driven Design principles.
SupaScore
83.25Best for
- ▸Design event-sourced aggregates with proper invariant boundaries for complex business domains
- ▸Implement projection rebuilding strategies for read model consistency across microservices
- ▸Architect saga patterns for distributed transaction coordination in event-driven systems
- ▸Design event schema evolution strategies for backward compatibility in long-lived systems
- ▸Implement CQRS command validation and event store selection for high-throughput domains
What you'll get
- ●Complete aggregate design with command handlers, event definitions, and invariant validation logic with specific code patterns
- ●Event store architecture recommendation with projection strategies, catch-up subscriptions, and consistency guarantees analysis
- ●Saga implementation pattern with compensation logic, timeout handling, and failure recovery mechanisms
Not designed for ↓
- ×Simple CRUD applications without complex business invariants or high scalability needs
- ×Real-time systems requiring strict consistency guarantees across all operations
- ×Legacy system integration where event sourcing overhead outweighs benefits
- ×Small applications with straightforward data models and minimal concurrent users
Complex business domain requirements with clear invariants, scalability constraints, and consistency requirements that justify the architectural complexity of CQRS/ES patterns.
Detailed architectural designs including aggregate boundaries, event schemas, projection strategies, saga orchestration patterns, and implementation guidance with specific technology recommendations.
