I will build your ai saas mvp in react node with openai claude

I've shipped React and Node apps for SaaS founders, agencies, and ecommerce teams.

 This gig is the AI-first version of that work: I build AI SaaS MVPs real production builds with OpenAI or Claude API

 integration, RAG over your data, Stripe billing, auth, and a clean React or Next.js frontend.

 Who this is for

 - Founders with an AI idea that needs to ship in weeks, not months

 - Teams that want a custom AI chatbot trained on their own docs (RAG)

 - Anyone tired of no-code AI tools that hit a wall after the demo

 What I build

 - React or Next.js frontend with streaming AI responses (Vercel AI SDK)

 - Node.js / Express backend wired to OpenAI, Claude, or Gemini

 - Vector search with Pinecone, pgvector, or Supabase for RAG / retrieval augmented generation

 - Auth (Auth.js or Clerk) and Stripe billing if you're charging users

 - Deployed to your Vercel / Railway / AWS account you own all source code and keys

 Stack

 JavaScript, TypeScript, React, Next.js, Node.js, Express, MongoDB, Supabase, Firebase, Vercel AI SDK, LangChain, OpenAI

 API, Anthropic Claude API, Pinecone, pgvector, Stripe, Tailwind CSS, Auth.js, Clerk.
