I will develop rest apis with java spring boot or node js
Vivek kumar
About this gig
Hi, I'm Vivek Kumar. I develop backend services and REST APIs using Java Spring Boot or Node.js.
I can help connect your web or mobile application to a structured backend with clear endpoints, input validation and MySQL integration.
Choose a package based on the number of endpoints and entities you need. All packages include source code and API examples or documentation. Premium includes JWT login and two user roles.
Please share your feature list, data structure and existing API requirements before ordering. We will agree the framework, endpoint list and deliverables first.
Frontend development, payment integration, complex reporting, hosting subscriptions and ongoing maintenance are outside these packages. Additional requirements need a separate quote.
Message me before ordering to confirm that your project fits the package.

FAQ
Can you use either Spring Boot or Node.js?
Yes. We will select one framework before ordering, based on your existing project and requirements. A package does not include separate implementations in both frameworks.
What counts as an endpoint?
One HTTP method and route combination counts as one endpoint. For example, GET /items and POST /items count as two endpoints.
Is authentication included?
JWT login and two user roles are included in Premium. Social login, OTP, complex permissions and third-party authentication require a separate scope discussion.
Is deployment included?
Hosting fees and production deployment are not included. I provide source code and setup instructions. Deployment work can be discussed separately.
