Top Rated
Project details
As an AI Developer, I built a customer service chatbot powered by GPT-based language models. This intelligent assistant can interact naturally with users—asking and answering questions, collecting structured data, and communicating with backend systems through API calls. Designed as part of a broader AI/Machine Learning solution, the chatbot improves customer support efficiency and enhances user experience through automation and real-time engagement.
