About this gig

Need an AI chatbot that actually knows your 

business, your documents, and your data?


I build custom AI chatbots and RAG systems that 

let your customers or team ask questions and get 

accurate answers powered by your own data, not 

just generic AI responses.


What I deliver:

· AI chatbot trained on your documents, website 

 or database

· RAG pipeline using LangChain, LlamaIndex and 

 OpenAI GPT-4

· Support for PDF, Word, Excel, CSV, URLs and 

 plain text

· Custom personality, tone and response style

· FastAPI or Node.js backend with REST API

· React or Next.js frontend chat interface

· Deployment on AWS, GCP, Vercel or Hostinger

· Full source code and documentation included


Perfect for:

· Customer support automation

· Internal company knowledge bases

· Document search and Q&A systems

· AI assistants for websites and apps


Message me before ordering I will review your 

requirements and confirm exactly what I will 

deliver and when.
