I will be your node js backend developer for rest api with nestjs or express

Need a Node.js backend developer to build a clean, fast and secure REST API? I'm a backend engineer with 15+ years of building Node.js systems, and I'll build your API in TypeScript with NestJS or Express.

What I'll build:

- REST APIs for web and mobile apps, with input validation and a clear structure

- JWT authentication, user roles and protected routes

- MongoDB, PostgreSQL or MySQL database design, with Redis caching

- Third-party API integrations: payments, email, webhooks and more

- Automated tests and Swagger (OpenAPI) docs

- Docker setup, plus optional deployment to AWS

What you get:

- Full source code in your GitHub repository

- Tests you can run with one command

- API docs and a short README on running and deploying it

I can also fix bugs in or add features to your existing Node.js backend.

How it works: message me with what you need, I confirm the scope and price, then I build, test and hand over with a short walkthrough.

Please message me before ordering so we can agree on scope.
