Node.js Development
Node.js powers our backend stack, and we build scalable APIs, WebSocket servers, and microservices that handle millions of requests efficiently. Whether using Express, NestJS, or raw Node.js, we have worked with every major framework and pattern in the ecosystem. Our Node.js expertise includes building RESTful and GraphQL APIs with proper authentication and validation, creating real-time applications with WebSockets and Socket.io, implementing microservices architectures with message queues, optimizing performance with clustering and caching strategies, and integrating with databases like MongoDB, PostgreSQL, and Redis.
We write clean, testable Node.js code that follows industry best practices for security, error handling, and scalability. Whether you need a simple API backend or a complex event-driven architecture, we deliver Node.js solutions that are robust, performant, and ready for production traffic at scale.

Our Process
A proven approach to delivering excellence at every stage of your project.
API Design and Documentation
We design clean, RESTful or GraphQL APIs with clear endpoints, consistent naming conventions, and proper HTTP status codes. Each API is documented using Swagger/OpenAPI or GraphQL introspection, includes versioning strategy, implements pagination and filtering, and provides comprehensive examples. We design APIs that are intuitive to use and easy to integrate, whether for your frontend team or third-party developers.
Database Integration
We integrate your Node.js application with the right database for your needs: PostgreSQL or MySQL for relational data, MongoDB for flexible document storage, Redis for caching and sessions, or a combination for polyglot persistence. We implement proper connection pooling, optimize queries for performance, handle database migrations with tools like Knex or Prisma, and establish backup and recovery procedures.
Authentication and Authorization
Security is built into every Node.js API we create. We implement robust authentication using JWT tokens, OAuth 2.0, or session-based auth as appropriate. We establish role-based access control (RBAC), implement proper password hashing with bcrypt, handle token refresh and revocation, protect against common vulnerabilities (SQL injection, XSS, CSRF), and integrate with identity providers like Auth0 or Okta when needed.
Performance Tuning
We optimize Node.js applications for high performance and scalability. This includes implementing caching strategies with Redis, using clustering to leverage multiple CPU cores, optimizing database queries and adding proper indexes, implementing connection pooling for databases and external services, using compression middleware, and profiling applications to identify and fix bottlenecks. We ensure your Node.js backend can handle production traffic efficiently.
Deployment and Monitoring
We deploy Node.js applications to production with proper DevOps practices: containerization with Docker, orchestration with Kubernetes or ECS, setting up load balancing and health checks, implementing graceful shutdown handling, configuring environment-specific settings, and establishing monitoring with Prometheus, Grafana, or Datadog. We set up logging aggregation, error tracking, and alerting to ensure your application runs reliably in production.
