Comprehensive backend development guide for Node.js/Express/TypeScript microservices. Use when creating routes, controllers, services, repositories, middleware, or working with Express APIs, Prisma database access, Sentry error tracking, Zod validation, unifiedConfig, dependency injection, or async patterns. Covers layered architecture (routes → controllers → services → repositories), BaseController pattern, error handling, performance monitoring, testing strategies, and migration from legacy patterns. Use when this capability is needed.

Backend Development Guidelines
Purpose
Establish consistency and best practices across backend services using modern Node.js/Express/TypeScript patterns. Service names in the examples are illustrative, not required project structure.
Blog API (✅ Mature) - Use as template for REST APIs
Auth Service (✅ Mature) - Use as template for authentication patterns
Anti-Patterns to Avoid
❌ Business logic in routes
❌ Direct process.env usage
❌ Missing error handling
❌ No input validation
❌ Direct Prisma everywhere
❌ console.log instead of Sentry
