About this gig

Need your app to talk to another service or add a useful AI feature? I integrate documented REST APIs and bounded AI text features into existing React, Next.js, TypeScript and Node.js applications.


Examples include sending data to a service, displaying API results, connecting transactional email, or adding a summarization or drafting flow. I implement server-side credential handling, request validation, loading/error states and verification notes for the agreed flow.


Basic: one documented REST endpoint in an existing app. Standard: one AI text feature OR up to three related REST endpoints. Premium: up to five related endpoints OR one AI flow saving output to an existing database.


Source changes and setup notes are included. You supply authorized API access and provider accounts. API usage, hosting, new app builds, model training, complex OAuth approvals and ongoing monitoring are separate.


Message before ordering with your stack, API documentation, desired input/output and acceptance example. We will confirm scope, dependencies and the right package. Never send live secrets in chat.
