I will build rest apis using nodejs, expressjs and typescript


About this gig
Need a reliable REST API for your application?
I can build backend API endpoints using Node.js, Express.js, and TypeScript with clean structure and practical error handling.
What I can build:
- REST API endpoints and CRUD operations
- Express.js routes and controllers
- MongoDB or PostgreSQL integration
- Request validation and error handling
- JWT authentication and protected routes
- Database models and API logic
- JSON responses with appropriate HTTP status codes
My process:
- Understand the required API behaviour.
- Design the relevant routes and data flow.
- Implement the backend logic.
- Add validation and error handling where required.
- Test the affected endpoints and provide a summary of the implementation.
I work with Node.js, TypeScript, Express.js, MongoDB, and PostgreSQL.
Packages cover the scope stated in each package. Large applications, complete backend systems, deployment, third-party integrations, and major architectural work are not included unless agreed separately.
Please provide the API requirements, expected request/response format, relevant database details, and existing project code if you are extending an application.

FAQ
What kind of APIs can you build?
I can build REST APIs for web and mobile applications using Node.js, Express.js, and TypeScript, including CRUD endpoints, authentication, validation, database operations, and structured error handling.
Can you add APIs to my existing project?
Yes. Please provide the relevant source code, existing API structure, database information, and the functionality you want to add. I can then work within the existing project structure.
Do you work with MongoDB and PostgreSQL?
Yes. I can integrate API endpoints with MongoDB or PostgreSQL and implement the required database operations.
Can you implement authentication?
Yes. JWT-based authentication and protected API routes can be included in the appropriate package. Please provide your existing authentication requirements if the project already has an auth system.
Can you build my entire backend?
Larger backend systems may require a custom scope rather than one of the standard packages. Please provide the requirements and existing architecture so the work can be scoped appropriately.
What do you need before starting?
Please provide the API requirements, expected endpoints, request and response examples, database information, and relevant existing source code if this is an existing application. Never send passwords, private keys, production secrets, or live database credentials.
