About this gig
Your business has the data. I turn it into an AI chatbot or AI agent that answers correctly - and takes action.
Not a Chatbase wrapper. I build custom RAG systems on your own stack: no per-message platform fees, you own everything.
WHAT I BUILD
- AI chatbot trained on your website, PDFs, docs, Notion or database - answers with sources, no made-up prices or policies
- AI agents that act: book appointments, qualify leads, update your CRM, send emails, trigger n8n / Make workflows
- Channels: website widget, WhatsApp, Slack, Telegram, mobile app or AI voice agent (I built B3 Voice, an AI call-center platform)
- Stack: OpenAI GPT, Claude, Gemini, LangChain / LangGraph, pgvector / Pinecone, Node.js, Python FastAPI, Next.js
- Admin dashboard: chat logs, analytics, retrain on new data in one click
HOW IT WORKS
- Scope chat - we define what the bot must answer and do, fixed quote
- I build it, you test it on real customer questions
- Deployed on Vercel / AWS / your VPS, full source code + docs
Senior full-stack & AI engineer, 6+ yrs, 70+ five-star Fiverr orders. 1-hour replies.
Message me with your use case and a data sample - I will tell you what is possible and what it costs.

FAQ
What do you need from me to get started?
Just two things: what the bot should answer or do, and a sample of your data (website URL, PDFs, docs, FAQ, product list or database export). I review it, tell you what is possible, and give you a fixed quote before you order.
Will the chatbot make things up (hallucinate)?
That is exactly what RAG solves. The bot answers only from your data, cites the source, and says 'I don't know' instead of guessing. We test it against your real customer questions before launch.
What does it cost per month to run?
Usually $5-$50/month in API usage for a small business - that's it. No per-seat or per-message platform fee, because the code and hosting are yours (Vercel, AWS or your VPS).
Can it connect to WhatsApp, my CRM or booking system?
Yes. Website widget, WhatsApp Business API, Slack, Telegram, HubSpot / GoHighLevel / custom CRM, Calendly, Stripe, Google Sheets, n8n / Make - any system with an API. Voice (phone) agents are available too.
Do I own the code and my data?
100%. Everything is delivered to your GitHub, deployed on your accounts, with docs and a video walkthrough. Your data stays on your servers and never trains a public model. No lock-in - any developer can maintain it later.
