Full Stack AI Engineer | OpenAI Chatbot, React.js, Node.js & Basic Customer Support Automation

I am looking for a Full Stack AI Engineer to build a simple AI-powered chatbot and basic customer support automation system for my business. The goal of this project is to create a lightweight AI chatbot that can answer common customer questions, collect basic customer details, reduce repetitive manual replies, and improve response time. I need a simple full-stack solution that includes an AI chatbot, basic backend APIs, database integration for storing conversations, and a clean frontend interface. The system does not need to be overly complex, but it should be reliable, easy to use, and easy to improve later. This project is best for someone who can build a small but functional AI chatbot system using OpenAI, React.js, Node.js, and a simple database setup.
