I will develop a backend rest api with node js, nest js

Is your backend slow to build, hard to maintain, or breaking on authentication?

I build REST APIs with Node.js, NestJS, TypeScript and PostgreSQL. I focus on the parts that usually fail later: authentication, validation, error handling, and a structure your team can keep working on.

What you get:

• REST endpoints (CRUD) with input validation
• PostgreSQL schema, relations and migrations
• JWT authentication (register, login, protected routes, refresh tokens)
• Clear error handling and HTTP status codes
• Swagger/OpenAPI docs you can test from the browser
• Full source code with setup instructions

Also available: roles and permissions, Stripe payments, third-party APIs, AI integrations, Docker and deployment.

How I work:

1. We go over what your API needs to do.
2. I define the endpoints and data model with you before coding.
3. I build and test the API.
4. I deliver working code you can run with one command.

I have 3+ years building backends for startups in Europe, the US and Latin America.

My goal is simple: an API that works today and is easy to extend tomorrow.

Send me a message and tell me what you're building.
