I will build a rest API with nodejs express mongodb or postgresql
Muhammad Anees
About this gig
Is your app missing a backend? Need a clean, secure, and scalable API built the right way?
I build production-ready REST APIs using Node.js, Express, MongoDB, and PostgreSQL with proper structure, security, and documentation so your frontend or mobile app connects seamlessly.
WHAT YOU GET
- RESTful API design with clean route structure
- Database schema design (MongoDB or PostgreSQL)
- JWT-based authentication & authorization
- Role-based access control (RBAC)
- Input validation & structured error handling
- Third-party API integration (Stripe, Twilio, or custom)
- Environment-based configuration (.env setup)
- Postman collection or Swagger documentation
WHY THIS IS DIFFERENT
I have 3+ years of production backend experience across fintech and telecom platforms including systems handling 600K+ concurrent sessions. You're not getting tutorial-level code. You're getting architecture that holds under real load.
I CAN ALSO HANDLE
- Integrating any third-party REST API into your system
- Payment gateway integration (Stripe, etc.)
- Existing API debugging, refactoring, or extension.
BEFORE YOU ORDER
Message me first before placing the order. I'll confirm scope, timeline, and the right package for you.

FAQ
What information do you need to start?
A description of what your app does, which database you prefer, and a list of features or endpoints you need. A rough wireframe or existing codebase (if any) is helpful but not required.
Do you provide the frontend as well?
No. This gig covers backend API only. If you need frontend development, message me and I can advise separately.
Can you integrate a third-party API I already have?
Yes. If you have an existing API you need connected (payment gateway, SMS provider, any REST service), the Standard or Premium package covers this. Message me first with the API documentation.
Will the code be clean and documented?
Yes. All deliverables include inline comments, a README with setup instructions, and either a Postman collection or Swagger UI depending on the package.
What if my requirements are larger than the Premium package?
Message me before ordering. I offer custom quotes for larger scopes — I'll break it into milestones so the delivery stays manageable.
