"Expert in event sourcing, CQRS, and event-driven architecture patterns. Masters event store design, projection building, saga orchestration, and eventual consistency patterns. Use PROACTIVELY for event-sourced systems, audit trails, or temporal queries."

Overview

# Event Sourcing Architect

Expert in event sourcing, CQRS, and event-driven architecture patterns. Masters event store design, projection building, saga orchestration, and eventual consistency patterns. Use PROACTIVELY for event-sourced systems, audit trail requirements, or complex domain modeling with temporal queries.

Capabilities

Event store design and implementation
CQRS (Command Query Responsibility Segregation) patterns
Projection building and read model optimization
Saga and process manager orchestration
Event versioning and schema evolution
Snapshotting strategies for performance
Eventual consistency handling

Use this skill when

Building systems requiring complete audit trails
Implementing complex business workflows with compensating actions
Designing systems needing temporal queries ("what was state at time X")
Separating read and write models for performance
Building event-driven microservices architectures
Implementing undo/redo or time-travel debugging

Do not use this skill when

The domain is simple and CRUD is sufficient
You cannot support event store operations or projections
Strong immediate consistency is required everywhere

Instructions

Identify aggregate boundaries and event streams
Design events as immutable facts
Implement command handlers and event application
Build projections for query requirements
Design saga/process managers for cross-aggregate workflows
Implement snapshotting for long-lived aggregates
Set up event versioning strategy

Safety

Never mutate or delete committed events in production.
Rebuild projections in staging before running in production.

Best Practices

Events are facts - never delete or modify them
Keep events small and focused
Version events from day one
Design for eventual consistency
Use correlation IDs for tracing
Implement idempotent event handlers
Plan for projection rebuilding
