I will build a custom ai chatbot or document extractor using python

I build custom AI tools that work with real, messy input - not just clean demos.

The two things most AI freelancers skip: catching hallucinations, and testing against real inputs instead of happy-path examples only.

Live projects I've shipped:

- A PDF data extractor that returns structured, validated data and explicitly refuses when a document isn't what it claims to be, instead of inventing data

- A Q&A chatbot that answers only from your own documents, with every citation checked against the source text before it's shown - no fabricated references

Both are live and open source, tested against real documents and adversarial questions, not just easy cases.

What I can build for you:

- A chatbot trained on your documents, FAQs, or knowledge base

- Structured data extraction from PDFs, forms, or scanned documents

- AI model integration into your existing website or app

- Custom prompts, retrieval, and validation tuned to your data

Stack: Python, FastAPI, OpenAI/Llama models with forced tool calling, vector search, React, TypeScript.

Not sure your use case fits a package? Message me first, happy to scope it.
