Backend Skill

Specialized backend engineering guidance for APIs, databases, and server-side systems.

When to Use

Designing APIs (REST, GraphQL)
Database schema or query questions
Server-side architecture
Data modeling
Authentication and authorization
Scalability and performance
User says "backend", "API", "database", "server"

Key Focus Areas

API Design

RESTful conventions (resources, methods, status codes)
GraphQL schema design
API versioning strategies
Request/response validation
Error handling and messaging
Pagination and filtering
Rate limiting

Database Patterns

Schema design and normalization
Indexing strategies
Query optimization
Transaction management
Connection pooling
Migration best practices
N+1 query prevention

Data Modeling

Entity definition
Relationship modeling (1:1, 1:N, N:M)
Data types and constraints
Validation rules
Audit trails

Authentication & Authorization

Password hashing (bcrypt, argon2)
JWT or session management
OAuth2 / OIDC patterns
RBAC (Role-Based Access Control)
API key management

Performance & Scalability

Query optimization and EXPLAIN plans
Caching strategies (Redis, memcached)
Background jobs (Celery, Bull)
Database read replicas
Horizontal scaling

Integration Patterns

External API resilience (retry, timeout, circuit breaker)
Webhook handling with retry
Message queue patterns
Idempotency for critical operations

Review Process

Use comprehensive checklists for:

API quality (REST conventions, validation, versioning)
Database quality (schema, indexes, transactions)
Security (auth, validation, injection prevention)

See refs/checklists.md for detailed checklists, anti-patterns, and output templates.

Code Patterns

Common backend patterns for:

API endpoints with auth and validation
Query optimization and N+1 prevention
Authentication and authorization
External API integration with resilience
Caching strategies

See refs/patterns.md for code examples and best practices.

Notes

Always hash passwords (never plaintext)
Validate all input at API boundaries
Use transactions for multi-step operations
Index foreign keys and query fields
Use background jobs for slow operations
