Implements scalable backend architecture, optimized API designs, and robust server-side patterns for modern Node.js and Next.js applications.

This skill equips Claude with a comprehensive library of industry-standard backend patterns and architectural best practices. It facilitates the implementation of structured patterns such as Repository and Service layers, advanced database optimizations like N+1 query prevention, and critical security features including Role-Based Access Control (RBAC) and rate limiting. It is particularly useful for developers building complex server-side systems who need to ensure high performance, maintainability, and enterprise-grade security using Node.js, Express, or Next.js.
