I will build a nodejs backend rest API
Miguel M
About this gig
Need a backend that is secure, fast and easy to maintain? I build REST APIs with NodeJS, Express and TypeScript, ready for your web or mobile app.
What I can build for you:
- REST APIs with clean, layered architecture
- PostgreSQL, MySQL or MongoDB databases with Prisma
- Secure login with JWT, refresh tokens and user roles
- Real-time features with WebSockets (orders, chats, live dashboards)
- Integrations with payments, WhatsApp and n8n automations
- Docker setup and automated tests in GitHub Actions
Why work with me:
- I recently built a live ordering system for a restaurant, with QR orders, a kitchen board and WhatsApp automation, used every day
- Input validation, rate limiting and security best practices from day one
- Full source code plus clear documentation and a Postman collection
- Clear communication in English and Spanish
How it works:
1. Tell me about your project before ordering
2. I send you a clear plan and the endpoint list
3. You get progress updates until delivery
Message me with your idea and I'll reply with a plan.

FAQ
Do I get the full source code?
Yes. Every package includes the complete source code, organized in a clean layered structure, plus setup instructions so you or your team can run and maintain it.
Can you work with my existing database or project?
Yes. I can connect to your existing PostgreSQL, MySQL or MongoDB database, or extend an existing NodeJS project. Share the details before ordering and I'll review it first.
Do you also build the frontend?
This gig focuses on the backend. If you need a simple React or NextJS frontend to go with it, message me and I'll send you a custom offer.
Will you deploy the API?
The Premium package includes deploy support. For Basic and Standard I deliver a Docker setup and clear instructions so you can deploy it on your own server or cloud provider.
How will I test the API?
You get a Postman collection with every endpoint ready to try, plus API documentation. Standard and Premium also include automated tests.
What do you need from me to start?
A short description of your app, the main features or endpoints you need, and any existing database or design. If you're not sure, we can define it together before you order.
