How does it handle security and authentication?

The skill includes standardized patterns for JWT token verification, middleware-based authentication, and granular Role-Based Access Control (RBAC).

Does this skill help with database performance?

Yes, it provides specific guidance on avoiding N+1 query problems, implementing cache-aside patterns with Redis, and optimizing SQL queries for efficiency.

What frameworks are supported by these patterns?

While the patterns are architectural and widely applicable, the provided implementation examples focus on Node.js, Express, and Next.js API routes.

Are these patterns suitable for high-traffic applications?

Absolutely. The skill includes advanced resilience patterns like exponential backoff retries, rate limiting, and structured logging necessary for production-grade systems.
