I will build a nestjs nodejs rest API backend with postgresql
OlgaFrolova
About this gig
Need a reliable REST API or backend for your web application?
I will build a clean and maintainable backend using NestJS, Node.js, TypeScript, PostgreSQL, and Prisma.
What I can build:
- REST API endpoints
- PostgreSQL database integration
- Prisma ORM setup
- JWT access & refresh authentication
- Role-based authorization
- DTO validation and error handling
- Existing third-party API integrations
- Secure and maintainable backend architecture
- Performance improvements and backend debugging
I have experience working with application architecture, authentication and authorization, API integrations, databases, real-time functionality, and existing codebases.
Package scope:
Each HTTP method + route counts as one endpoint. For example, GET /users and POST /users are two endpoints.
Complex third-party integrations, OAuth, payment systems, WebSockets, major infrastructure work, or requirements beyond the selected package may require a custom offer.
Please contact me before ordering if you have a complex or existing backend project.

FAQ
What technologies do you use?
I primarily work with NestJS, Node.js, TypeScript, PostgreSQL, and Prisma. I can also work with REST APIs, JWT authentication, Socket.IO, and existing backend codebases.
What counts as one API endpoint?
One HTTP method and route counts as one endpoint. For example, GET /users, GET /users/:id, and POST /users are three separate endpoints.
Does the backend include authentication?
JWT authentication is included in the Standard and Premium packages. It can include access and refresh token flows. Advanced authentication requirements may require a custom offer.
Do you provide the source code?
Yes. Source code is included with every package. The project will be delivered with a clear and maintainable structure.
Can you integrate third-party APIs?
Yes. I can integrate an existing documented third-party API. One API integration is included in Premium, or it can be purchased as a Gig Extra. Complex integrations may require a custom offer.
Can you work with my existing NestJS backend?
Yes. I can add endpoints, database functionality, authentication, integrations, or other backend features to an existing project. Please contact me first if the codebase is large or complex.
