Node.js Development
Professional Node.js development services. Backend systems, REST and GraphQL APIs, realtime applications, database architecture, and third-party integrations built for performance and scalability.
What I do
Full-service Node.js development covering REST APIs, GraphQL, realtime systems, microservices architecture, third-party integrations, and database design. Building robust backend solutions that scale.
REST API Development
Building robust REST APIs with Express, Fastify, or NestJS. Clean architecture, comprehensive documentation, authentication, and rate limiting built in.
GraphQL APIs
Flexible GraphQL APIs with Apollo Server or Yoga. Efficient data fetching, type safety, and schema-first development for complex data requirements.
Realtime Systems
WebSocket-based realtime applications using Socket.io or ws. Live updates, chat systems, collaborative tools, and event-driven architectures.
Microservices Architecture
Designing and implementing microservices with clear boundaries, message queues, and service communication. Scalable systems that grow with your needs.
Third-Party Integrations
Connecting your systems with external APIs and services. Payment gateways, CRM platforms, shipping providers, and business tool integrations.
Database Architecture
Designing efficient database schemas for PostgreSQL, MySQL, or MongoDB. Query optimisation, indexing strategies, and data migration scripts.
Problems I solve
Helping businesses build scalable backend infrastructure and reliable APIs. Moving from limited, slow systems to robust architectures that support growth and enable automation.
The Problem
Backend systems that cannot handle growing traffic or data volume
The Solution
Architecting scalable Node.js applications with proper caching, database optimisation, and horizontal scaling strategies. Load testing and performance tuning throughout development.
The Problem
Slow API response times affecting user experience and system performance
The Solution
Implementing caching layers with Redis, database query optimisation, and efficient data fetching patterns. Async operations and connection pooling for maximum throughput.
The Problem
Disparate systems requiring manual data entry and reconciliation
The Solution
Building API integrations that automate data flow between systems. Webhooks for realtime updates and error handling for reliability.
The Problem
Need for realtime features like live updates, notifications, or collaboration
The Solution
Implementing WebSocket-based realtime communication. Event-driven architecture with Socket.io or similar libraries for bidirectional communication.

Frequently asked questions
Common questions about Node.js development. If you have a specific question not covered here, feel free to get in touch.
Node.js excels at I/O-heavy applications like APIs, realtime systems, and microservices. It is particularly suitable for applications requiring high concurrency, such as chat applications, streaming services, or API gateways. For CPU-intensive tasks, other runtimes may be more appropriate, though Node.js can still handle them with proper architecture.
Express is minimal and flexible, suitable for simple APIs and quick prototypes. Fastify focuses on performance with built-in validation and serialization. NestJS provides a structured, Angular-like architecture with TypeScript support, dependency injection, and modules - ideal for large-scale applications. I recommend based on your project complexity and team familiarity.
Yes. I build realtime applications using Socket.io or ws library. Common use cases include live notifications, chat systems, collaborative editing, dashboards with live data, and multiplayer features. Socket.io provides automatic reconnection and fallback mechanisms for production reliability.
Security is implemented at multiple layers: authentication with JWT or OAuth, input validation, rate limiting, CORS configuration, and SQL injection prevention. Sensitive data is encrypted, and APIs follow OWASP guidelines. Security testing is performed throughout development.
Yes. I regularly work with existing projects for improvements, feature additions, or modernisation. This includes refactoring legacy code, adding new endpoints, improving performance, migrating to newer Node.js versions, and updating dependencies. I can audit your current codebase and provide recommendations.
PostgreSQL is my default choice for relational data - it is robust, well-supported, and offers advanced features. MongoDB works well for document-based or flexible schemas. Redis is excellent for caching and session management. The choice depends on your data patterns, query requirements, and scalability needs.
