I will do API development and integration

Need a Node.js API built, integrated or repaired?

I work with Express REST APIs. Depending on the agreed scope, I can build endpoints, connect an existing service, add validation or authentication, fix a backend issue, and provide tests and clear setup notes.

I have worked on custom Node.js APIs and data/API integrations. I will check your specific third-party service before quoting it; I do not claim to have delivered every integration.

You will receive the agreed code changes, instructions to run them, and a summary of what was tested. Documentation, Docker setup and broader test coverage can be included when they are written into the package or custom offer.

Please message me first with the API specification or problem, your existing stack, required access and deadline. I'll confirm a realistic scope and price before you order. Client-owned accounts and credentials must be available for third-party integrations.
