About this gig

Do you need an AI chatbot that answers from your own documents instead of giving generic responses?


I will build a custom RAG chatbot for your PDFs, website, knowledge base or company data. The chatbot will retrieve relevant information before answering and can display source references for greater transparency.


I can provide:

  • PDF, Word, CSV and website data ingestion
  • Semantic or hybrid search
  • Source citations
  • Conversation history
  • OpenAI, Claude or Gemini integration
  • Pinecone, Qdrant, Chroma or PostgreSQL vector search
  • FastAPI backend
  • React or Next.js chat interface
  • Authentication and cloud deployment


My stack includes Python, FastAPI, LangChain, LangGraph, PostgreSQL, Supabase, React, Next.js, Docker and AWS.


You will receive maintainable source code and setup documentation.


Please message me before ordering with your data type, number of documents and expected users.
