I will develop a scalable backend architecture with node js


About this gig
Need a backend that will not fall over once real traffic hits it?
I build REST APIs and database architecture with Node.js and PostgreSQL secure, properly structured, and ready to scale as your product grows.
What you get:
- REST API built with Node.js and Express
- PostgreSQL schema design, normalized and indexed properly
- Authentication and role-based authorization
- Third-party integrations (payments, email, storage, etc.)
- Input validation and error handling done right
- API documentation
- Deployment and environment setup
How I work:
- We lock the scope endpoints, data model, integrations
- I design the database schema and API structure
- I build the backend, with regular progress check-ins
- We test every endpoint against the agreed scope
- I deploy and hand over source code and documentation
You get clear communication throughout, not silence until delivery day, plus bug support tied to the agreed scope after launch.
Every backend is different before ordering, message me your feature list, expected data model, integrations, and existing code if any, and I will tell you honestly what fits.
Third-party fees and out-of-scope features are not included.

FAQ
What if I already have a partial API?
Send it over — I'll assess what to extend versus rebuild.
Do you handle authentication?
Yes, JWT/session-based auth and role permissions are standard.
Can this scale to high traffic?
Yes — schema and query patterns are built with scaling in mind from day one, not bolted on later.
Do you deploy it, or do I?
I can deploy to your preferred host (Railway, AWS, etc.) as part of the package.
Is API documentation included?
Yes, every package includes documentation (Postman collection or equivalent) so your frontend team can integrate without guessing.
