About this gig

Build a dependable AI chatbot that answers from your documents, PDFs, website content, or knowledge base.


I will create a Retrieval-Augmented Generation (RAG) workflow that retrieves relevant information before the model responds, helping improve accuracy and provide source-aware answers.


I can deliver:


Document or PDF ingestion and cleaning

Chunking, embeddings, and vector search

Chatbot connected to your private knowledge base

OpenAI, Claude, Gemini, or open-source model integration

Pinecone, Qdrant, Chroma, FAISS, PostgreSQL/pgvector, or Supabase

FastAPI endpoints and database integration

Metadata filters, citations, testing, and setup documentation


You receive maintainable Python source code and a clear handoff. Standard and Premium packages support more complete, production-oriented workflows. Exact document volume, integrations, interface, and deployment must be agreed before ordering.


Please message me with your data sources, expected users, preferred model, current stack, and hosting requirements so I can confirm the right package.
