Project details
Looking for a custom AI chatbot that actually understands your business? I build intelligent, production-ready chatbots and conversational AI assistants powered by the latest LLMs GPT-5, Claude, and open-source models like LLaMA.
Whether you need a customer-support bot that answers from your own documents, a lead-generation assistant for your website, or a multi-agent system that handles complex workflows, I deliver a solution that's accurate, scalable, and tailored to you.
What I build:
• Custom GPT & Claude-powered chatbots
• RAG chatbots trained on your docs, PDFs & knowledge base
• Multi-agent systems with LangChain & LangGraph
• Website, WhatsApp, Slack & Telegram integration
• Vector database setup (Pinecone, Qdrant, ChromaDB)
• Secure API integration & deployment
Why work with me:
✅ Top Rated Plus top 1% of talent on Upwork
✅ $100K+ earned across 89+ projects
✅ 9,900+ hours of proven delivery
