## Profile Tips for Node.js Developers

1. ### Show API Design Excellence  
   Include well-documented REST or GraphQL APIs. Clean endpoints, proper error handling, and OpenAPI specs impress founders.

2. ### Demonstrate Performance Knowledge  
   Show you understand the event loop, async patterns, and how to avoid blocking operations. Mention specific performance optimizations.

3. ### Include Real-Time Features  
   Node excels at real-time. Include a project with WebSockets, SSE, or similar. Chat apps, live dashboards, or notifications work great.

4. ### Show Production Awareness  
   Include error handling, logging, monitoring, and graceful shutdown patterns. Show you can build production-ready services.
