About this gig

Want your team or customers to ask questions and get answers straight from your PDFs, with the page they came from?


I build document chatbots (RAG) that answer from YOUR files, quote the source and say "I don't know" instead of making things up.


WHAT MAKES MINE DIFFERENT

- Understands tables and charts, not just plain text

- Hybrid search (keyword + semantic) with reranking for accurate answers

- Every answer cites the document and page

- Streaming answers, like ChatGPT

- Works with OpenAI, Gemini or a private local model


REAL PROOF

I built an agentic RAG system (FastAPI, LangGraph, Next.js) that parses PDFs into text, tables and figures, rewrites questions, retrieves with hybrid search, reranks, checks its own answer and retries if it is weak. It traces every step so you can see why it answered.


GOOD FOR

- Company knowledge bases, SOPs and policies

- Product manuals and support docs

- Research papers and reports

- Course or training material


YOU GET

Source code, a working web app, setup docs and a walkthrough video.


Send me a sample PDF and your use case and I'll recommend the right package.
