About this gig

I will build a secure, scalable, and high-performance REST API using Node.js and Express.js, with MongoDB or PostgreSQL database integration.


My API development services include:

  • RESTful API development with Node.js & Express.js
  • MongoDB or PostgreSQL database integration
  • CRUD operations and database relationships
  • JWT authentication and authorization
  • Request validation and error handling
  • API testing with Postman
  • Clean, maintainable, and well-structured code
  • Source code included
  • Bug fixing and existing API improvements


Whether you need a new backend API, authentication system, database-driven application, or want to integrate an API into your existing project, I can build a reliable solution according to your requirements.


Tech Stack:

Node.js | Express.js | MongoDB | PostgreSQL | REST API | JWT | Swagger UI | Postman
