Node.js is one of the most in-demand backend technologies globally. It's the foundation of Express.js (most popular Node framework) and NestJS (enterprise-grade). Indian startups (Razorpay, PhonePe, Meesho) heavily use Node.js backends, making it a critical skill for 2026.
Node.js is a JavaScript runtime built on Chrome's V8 engine that allows JavaScript to run on the server side. It enables full-stack JavaScript development and is known for its non-blocking, event-driven architecture.
List 'Node.js' with associated frameworks (Express.js, NestJS) and mention it in context of what you built — API servers, real-time apps, microservices. Include your API scale (requests/day) and any performance optimizations.
Use these as inspiration. Always customize with your own numbers and context.
“Backend developer using Node.js”
“Built Node.js/Express REST API serving 500K daily requests with 99.99% uptime; implemented rate limiting and JWT auth for 10K+ users”
“Created API with Node and Express”
“Developed Node.js WebSocket server handling 1,000 concurrent real-time connections for a collaborative editing feature”
“Node.js experience in projects”
“Built Node.js microservices architecture (8 services) using gRPC + RabbitMQ, reducing inter-service latency by 60%”
Include these naturally in your resume. ATS systems scan for exact keyword matches.

List both. Node.js is the runtime (always list it). Express.js, NestJS are frameworks built on top — list whichever you've used. ATS searches for all separately.
Excellent for I/O-heavy applications (APIs, real-time apps, streaming). Not ideal for CPU-heavy tasks. For most startup/product company backends, Node.js is a great choice.
Node.js: best for JavaScript devs and real-time apps. Python: best for data/ML integration. Java: best for high-throughput enterprise systems. All are in-demand; choose based on your existing JS knowledge.
NestJS is an enterprise-grade Node.js framework with TypeScript, decorators, and module architecture. If you know it, definitely add it — NestJS experience commands a 10-20% salary premium over Express.
Handling 1,000+ RPS (requests per second) in production is impressive. For a resume bullet, say 'served X requests/day' — it's easier to understand than RPS for non-technical recruiters.
