About this gig
Your documents have the answers. Your users just cannot find them.
I build production ready web apps where users upload any PDF and instantly ask questions in plain English powered by OpenAI and a RAG pipeline that retrieves the exact answer from the right page.
Not a demo. Not a prototype. A fully deployed web application your users can start using on day one.

- PDF upload with automatic text extraction and chunking
- RAG pipeline with vector embeddings for accurate retrieval
- OpenAI GPT4 powered Q&A interface
- Chat history so users can revisit previous conversations

- User authentication with Clerk or Supabase Auth
- Deployed on Vercel with your custom domain
- Full source code and documentation
My stack:
Next.js, React, TypeScript, OpenAI API, LangChain, Pinecone, Supabase, Tailwind CSS, Clerk, Vercel
