I will build a small nodejs rest API or backend feature

Need a focused Nodejs backend task completed with clear scope and maintainable code?

I can build a small REST API, add endpoints to an existing Express project, connect database operations, implement input validation, add authentication logic, or integrate a third party API.

What I can help with:

REST endpoints and CRUD operations

Express routes controllers and middleware

MongoDB PostgreSQL or MySQL integration

Request validation and error handling

JWT based authentication

API documentation and setup notes

Focused tests when included in the selected package

Please message me before ordering if your task involves an unfamiliar codebase, deployment, payments, real time features, or a complex external service. I will review the scope so the package matches the work.

You will receive the agreed source code changes and clear instructions for running them. Hosting, paid services, production credentials, and third party fees are not included unless stated in a custom offer. A revision covers an adjustment to the agreed feature, not an additional endpoint or a new feature.
