Hire Node.js developers who understand the event loop, not just the framework. Production Node.js requires: proper async/await patterns (not callback hell), connection pool management for databases, error handling that doesn't crash the process, memory leak prevention, and the streaming patterns that handle large payloads without buffering everything in memory.
Production Node.js demands: NestJS or Express with proper middleware chains, TypeScript for type safety, database integration (PostgreSQL, MongoDB) with ORM (Prisma, TypeORM), authentication (JWT, OAuth), rate limiting, logging, and 12-factor app patterns for cloud deployment.
