Hammad Durrani
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.
