About this gig

Turn your existing Next.js or React app into a working AI feature, not just an API demo.


I build or repair one focused feature:


- customer or internal chatbot

- Q&A or search over approved documents

- summarization, classification, or data extraction

- structured output or workflow automation

- streaming responses and conversation state


I can connect OpenAI or Claude through secure server-side routes, protect API keys, validate model output, handle errors and limits, connect your existing auth or database, and test the agreed flow in production.


Why work with me:


- 20+ years shipping production web apps

- 5-star Fiverr delivery covering Claude API, authentication, Stripe, and launch

- personally implemented, reviewed, and tested

- fixed scope and clear async updates


This Gig is for an existing app, not an unlimited build from scratch.


Message me first with your repo or preview, desired user outcome, current problem, data source, and hosting target. I will recommend the smallest reliable package.
