I will build a nestjs backend API with postgresql
Darshan R.
About this gig
Need a clean, reliable backend for your web or mobile app? I will build a REST API with NestJS and TypeScript, store the data in PostgreSQL with Prisma, and document every endpoint with Swagger, so your frontend developer can start right away.
What you get:
- Well-structured NestJS modules, easy to extend
- Request validation with clear error messages
- PostgreSQL database with migrations (Prisma)
- Swagger (OpenAPI) documentation for every endpoint
- JWT login and roles (Standard and Premium)
- Docker Compose setup, so it runs with one command
- Unit and end-to-end tests (Premium)
- A short README that explains how to run and deploy it
I have built production backends for clients in Korea: a hospital revenue platform with payment and bank integrations, and IoT backends. You can see my code style here: github.com/Darshan0502/iot-monitor
Please message me before ordering, so we can agree on the exact scope.

Full stack developer with 2+ years of experience, focused on the backend: NestJS, Node.js, TypeScript and PostgreSQL, with Next.js and React on the front end. I have built production systems for clients in Korea, including a hospital revenue platform with payment gateway, card and bank data integrations, and IoT backends that receive device data over MQTT, raise alerts and push live updates. I write clean, typed code with validation, API docs and tests. Open-source example: github.com/Darshan0502/iot-monitor

FAQ
Can you work on my existing NestJS or Express project?
Yes. Share the repository and tell me what you need, and I will tell you the cost and time before you order.
Do I get the full source code?
Yes, in every package. The code is yours.
Can you also deploy it?
I can deploy to a server or service you already have (for example a VPS, Render or Railway). Hosting costs are paid by you.
