Built a domain-specific AI chatbot similar to GPT, customized to understand and respond using industry-focused knowledge. The system is trained and tuned with proprietary data to deliver accurate, context-aware answers. It supports natural multi-turn conversations with memory and intent handling. I implemented a clean, user-friendly chat interface optimized for web and mobile. The backend is scalable, secure, and API-driven to handle high traffic reliably. The solution is designed for easy updates as domain data and business needs evolve.
