I will build a scalable rest API with nodejs, expressjs or nestjs


Over deze dienst
Need a REST API developer for your Node.js application?
I will develop, extend, or improve REST APIs using Node.js, Express.js, or NestJS. Whether you need new API features, additional endpoints, database operations, authentication, or backend improvements, I can help build reliable server-side functionality tailored to your application.
I can work with both new and existing projects, including:
REST API development and new endpoints
CRUD operations and business logic
PostgreSQL or MongoDB integration
JWT authentication and authorization
Request validation and error handling
Pagination, filtering, and sorting
Third-party API integrations
Existing API improvements and extensions
React and Next.js frontend integration
I focus on clean architecture, maintainable code, reliable API behavior, and secure backend development.
Have an existing Node.js API that needs new functionality or improvements? Send me your requirements and I'll help you move it forward.
