I will build a custom ai chatbot using langgraph, rag, and openai
Arif Ahmad Khan
About this gig
Looking for a chatbot that actually understands your business not just a generic ChatGPT wrapper?
I build custom AI chatbots using LangGraph, LangChain, and RAG (Retrieval Augmented Generation), trained on your own documents, FAQs, and data so every answer is accurate and on brand.
I currently work as an AI Engineer for a Dublin based company, where I built a production voice enabled executive assistant and an AI tax workflow copilot real systems handling real business operations, not portfolio demos.
What I offer:
Custom RAG chatbots trained on your documents (Pinecone, FAISS, Weaviate)
LangGraph multi agent orchestration for complex workflows
Integration with your website, WhatsApp, Slack, or Telegram
FastAPI backend, Docker deployment
CRM/database integration
Clean, documented, production-ready code
Whether you need a simple FAQ bot or a fully orchestrated AI agent handling customer support, lead qualification, or internal operations I'll build it right the first time.
Let's turn your business knowledge into a chatbot that actually helps your customers.
Message me before ordering if your use case needs a custom scope happy to advise on the right package.

I also run an AI automation agency, so one order gets you a web developer and an AI engineer in the same person. Stack: React, Next.js, TypeScript, Node.js, Python, FastAPI, LangGraph, n8n.
Fast delivery, clear communication, and revisions until you are happy. Message me with your idea and I will send you a plan and an exact quote, free.
My Portfolio
FAQ
What's the difference between the packages?
Basic is a simple GPT chatbot with pre-set flows. Standard adds RAG so the bot learns from your actual documents. Premium includes full LangGraph orchestration, CRM integration, and source code for production use.
Do I need to provide my own OpenAI/API key?
Yes, you'll need your own API key (OpenAI, Anthropic, etc.) since usage costs are billed directly by the provider based on your bot's traffic. I'll guide you through setup.
Can you integrate the chatbot with my existing website or CRM?
Yes , I regularly integrate chatbots with websites, WhatsApp, Slack, Telegram, and CRM/database systems. Message me your specific stack before ordering so I can confirm compatibility.
How do revisions work?
Each package includes a set number of revisions (see package details). Additional revisions can be purchased as a gig extra if needed beyond that.
