I will build a rest API backend with nodejs express and postgresql

You need an API that other people can build against without asking you questions every day. That means predictable routes, real validation, errors that say what went wrong, and a database schema that will not need rewriting in three months.

Four years building Node and PostgreSQL backends in production, as the only engineer accountable for them.

WHAT YOU GET

Basic - Up to 8 endpoints with validation, error handling and a documented schema. 4 days.

Standard - Up to 20 endpoints, plus JWT authentication, role-based access, pagination and filtering. 10 days.

Premium - Everything in Standard plus S3 file uploads, background jobs, rate limiting, Docker setup and API documentation for your frontend team. 14 days.

HOW IT WORKS

1. We agree the endpoint list and data model in writing before any code.
2. 2. You get the schema and migrations first, so structural mistakes surface early and cheaply.
3. 3. Delivered as pull requests with setup instructions that work on a clean machine.

Every package includes input validation and consistent error responses. A backend without them is not finished, so they are not an upsell.

Message me with what you are building and I will tell you which package fits.
