I will nestjs rest API with authentication

Need a backend that holds up in production, or help with one you already have? I build REST APIs with NestJS and TypeScript, and I fix and extend existing Node.js backends.

What you get: Modular NestJS code that is easy for other developers to work on; JWT login with refresh tokens and role-based access for admins and users; PostgreSQL or MongoDB, with validated input and consistent error responses; bug fixes and new features in your existing NestJS or Express.js code; automated tests and a Docker setup, so the API is easy to run and deploy

My background: I am a full-stack engineer with 4+ years of experience. Most recently, I migrated a live production API from Express.js to NestJS as the only engineer on the project. I also maintain an open-source NestJS backend that supports 6 login methods, including refresh-token rotation, two-factor authentication, and passkeys.

I test every change before delivery and explain how the code works, so you are not left with code nobody understands.

Please message me before ordering with a short description of your project, so I can confirm the right package and delivery time.
