About this gig

Need a custom AI chatbot that understands your business, products, services, and documents?


I will build a custom AI knowledge base chatbot tailored to your business using OpenAI GPT, RAG, LangChain, and modern full-stack technologies.


Your chatbot can:

  • Answer questions from your business knowledge base
  • Use PDFs, documents, FAQs, and custom data
  • Provide accurate AI-powered responses using RAG
  • Integrate with your website or web application
  • Connect with databases, APIs, CRM systems, and other tools
  • Support customer service and business automation
  • Include authentication, conversation history, and custom UI when required


I can build anything from a simple AI chatbot to a complete production-ready AI assistant with a custom frontend, backend, database, and API integrations.


Tech stack: React, Next.js, Node.js, Express.js, TypeScript, MongoDB, OpenAI, LangChain, Pinecone, and more.


Why me?

  • Senior full-stack development experience
  • Clean and scalable architecture
  • Custom solutions not templates
  • Responsive and user-friendly UI
  • Deployment and integration support


Message me with your requirements before ordering, and I'll recommend the best AI chatbot solution for your project.
