Node.js Development

Node.js's non-blocking, event-driven architecture makes it perfect for I/O-heavy applications: APIs, real-time chat, streaming services, and microservices. It handles thousands of concurrent connections without breaking a sweat.

Companies like Netflix, PayPal, LinkedIn, and Uber use Node.js in production. PayPal reported 35% faster response times after switching from Java to Node.js. It's proven at massive scale.

Using JavaScript on both frontend and backend means shared code, shared types, shared logic. Your API response types match your frontend interfaces. No more guessing what shape the data will be in.

I build RESTful APIs and GraphQL endpoints that are well-documented, properly authenticated, and designed to handle real-world traffic. Rate limiting, input validation, error handling: all the things that separate a hobby project from production software.

For real-time features, I implement WebSocket connections with Socket.io: live chat, notifications, collaborative editing, real-time dashboards. The kind of features that make your app feel alive.

I also handle database design, caching strategies, job queues, and third-party integrations. Whether you need to connect to a payment processor, send emails, or sync with an external CRM, I've done it.
