Design efficient NoSQL data models for MongoDB, DynamoDB, and Cassandra — applying embed-vs-reference, access-pattern-first, sharding key, and index strategies. Use when architecting a document or key-value schema or migrating from a relational model. Trigger with \"design NoSQL schema\", \"model for MongoDB\".

# NoSQL Data Modeler
Design efficient NoSQL data models for document and key-value databases.
## NoSQL Modeling Principles
1. **Embed vs Reference**: Denormalization for performance
2. **Access Patterns**: Design for queries, not normalization
3. **Sharding Keys**: Distribute data evenly
4. **Indexes**: Support query patterns
## MongoDB Example
```javascript
// User document with embedded posts (1-to-few)
{
_id: ObjectId("..."),
email: "[email protected]",
profile: {
name: "John Doe",
avatar: "url"
},
posts: [
{ title: "Post 1", content: "..." },
{ title: "Post 2", content: "..." }
]
}
```
## When to Activate
Design NoSQL schemas for MongoDB, DynamoDB, Cassandra, etc.
Expert backend architect specializing in scalable API design, microservices architecture, and distributed systems. Masters REST/GraphQL/gRPC APIs, event-driven architectures, service mesh patterns, and modern backend frameworks. Handles service boundary definition, inter-service communication, resilience patterns, and observability. Use PROACTIVELY when creating new backend services or APIs.
Master Django 5.x with async views, DRF, Celery, and Django Channels. Build scalable web applications with proper architecture, testing, and deployment. Use PROACTIVELY for Django development, ORM optimization, or complex Django patterns.
Build high-performance async APIs with FastAPI, SQLAlchemy 2.0, and Pydantic V2. Master microservices, WebSockets, and modern Python async patterns. Use PROACTIVELY for FastAPI development, async optimization, or API architecture.
