I will develop a rest API backend using nodejs and express
Kelvin S
About this gig
I will build a custom REST API backend using Node.js, Express.js and JavaScript.
My service focuses on backend and API development. I can create REST endpoints, CRUD operations, business logic, request validation, error handling, database integration, environment configuration, testing and API documentation according to your project requirements and selected package.
You will receive clean and organized source code with instructions to configure and run the project.
Third-party API integrations may be available depending on the project and must be discussed before ordering. If an external service such as Google Maps Platform is required, the client must provide their own valid API key, account and credentials. Any subscriptions or usage fees charged by third-party services are the client's responsibility.
Hosting, deployment, domains, cloud services and other paid infrastructure are not included unless agreed before ordering.
Please contact me before ordering to discuss your requirements.
