About this gig

Your team answers the same questions all day. Customers wait, leads go cold, and your best info sits in PDFs nobody opens.


I build AI chatbots that actually read your stuff: your website, PDFs, help docs, Notion. The method is called RAG. Plain English? Before the bot answers, it looks things up in your files, like a good employee checking the manual. So it sticks to the facts instead of making things up.


My numbers:

- 99.5% answer accuracy on a client's Q&A test

- 2,000+ messages a day handled by one bot

- 8 years building software, 6 in AI


Why people hire me:

- Answers come from your content, with sources

- Runs on your site, Slack, WhatsApp or Discord

- Hands off to a real person when it should

- You own the code. No monthly fee to me


Tech stack: Python, OpenAI GPT, Claude, LangChain, pgvector or Pinecone, Next.js, AWS


How it goes:

1. You send your docs and top 10 customer questions

2. I build the bot and test it on those questions

3. You try it and tell me what to tweak

4. I launch it and hand over code and a simple guide


Ben Franklin said time is money. Send me the one question you're tired of answering, and I'll show you how the bot would handle it.
