I will build a scalable node js backend and rest API
KRANTHI KUMAR A
About this gig
Need a reliable Node.js backend or REST API for your application? I can help.
I build clean, secure, and scalable backend systems using Node.js, Express.js, REST APIs, PostgreSQL, Redis, and JavaScript.
What I can build:
REST APIs and backend services
Authentication and authorization
Database integration
API validation and error handling
Third-party API integrations
Performance-focused backend architecture
Automated testing and clean code
What you get:
Well-structured, maintainable code
Secure API implementation
Database integration when included
Source code
Testing and error handling
Clear communication throughout the project
I focus on building production-ready solutions rather than just making an API that works.
Have a larger or custom backend project? Message me before ordering so I can recommend the right package.

What do you need from me to start?
Please provide your API requirements, endpoint details, preferred database, authentication requirements, API documentation or references if available, and any existing code or repository that needs to be integrated.
Can you integrate my existing database?
Yes. I can integrate supported databases such as PostgreSQL and MySQL. Database integration is included in the Standard and Premium packages, while other requirements can be handled through a custom offer.
Can you build authentication?
Yes. I can implement secure authentication and authorization based on your project requirements, including token-based authentication and role-based access control.
Can you integrate third-party APIs?
Yes. I can integrate external REST APIs and services into your backend. Please provide the API documentation and explain the required workflow.
Do you provide the source code?
Yes. Source code is included with every package.
Can you work with an existing Node.js project?
Yes. I can extend existing Node.js backends, add endpoints, integrate databases or external APIs, improve performance, and fix backend issues.
Can you deploy the backend?
Deployment can be included for suitable projects through a custom offer. Please tell me your hosting platform and deployment requirements before ordering.
What if my project is larger than the Premium package?
No problem. Send me your requirements before ordering. I can review the scope and create a custom offer for larger or more complex backend systems.
Do you provide documentation?
Basic documentation and setup instructions can be included depending on the package. Detailed documentation can also be added to a custom offer.
Can you build a complete backend from scratch?
Yes. I can build a Node.js backend from the ground up, including API architecture, authentication, database integration, validation, error handling, testing, and integrations based on the selected package.
