About this gig

Need an AI chatbot that answers from YOUR documents instead of making things up? I build custom RAG chatbots that cite the exact page every answer came from.


WHY MINE ARE DIFFERENT

Most developers ship on guesswork. I benchmark retrieval accuracy on a public dataset before delivery, so you get measured numbers. On my last build I rejected a popular reranking method because it measured 8.4% WORSE, and shipped hybrid search instead.


WHAT YOU GET

- Answers from your PDFs, contracts and manuals

- The source page cited for every claim

- "I don't have that information" instead of hallucinating

- Hybrid semantic + keyword search

- Web chat interface or REST API

- Full source code


TECH

Python, FastAPI, LangChain, ChromaDB, Pinecone, OpenAI GPT, Claude, Gemini, or local Ollama models.


100% PRIVATE

Runs on your own server - documents never leave it. Ideal for legal, medical and financial data.


PERFECT FOR

Knowledge base chatbot, customer support, contract and policy Q&A, research search, compliance manuals.


Message me your document type and 3 example questions and I'll say honestly whether RAG fits.
