You will get a scalable Node.js Express or NestJS REST API
Project details
Need a reliable REST API for your web application?
I will build a clean and scalable REST API using Node.js, Express.js, or NestJS, tailored to your project requirements.
I can develop CRUD APIs, authentication and authorization, database integration, validation, error handling, pagination, filtering, and business logic. I work with PostgreSQL and MongoDB and can integrate APIs with your existing Next.js, React, or other frontend application.
What you can get:
• REST API with clearly structured endpoints
• Node.js + Express.js with JavaScript
• Node.js + NestJS with TypeScript
• PostgreSQL or MongoDB integration
• JWT authentication and authorization
• Request validation and error handling
• Pagination, filtering, and sorting
• Clean and maintainable source code
I focus on secure architecture, maintainable code, and reliable API behavior. Whether you need a simple CRUD API or a more advanced backend, I can build a solution ready to integrate with your frontend.
Send me your requirements and let’s build your API.
