Most AI chatbots take 30+ seconds to reply and fail to capture leads. I architected this Enterprise Agentic OS to solve that. Built with a custom Next.js frontend and an asynchronous n8n backend, this system delivers sub-4-second RAG responses using Pinecone and Gemini. While the user receives instant answers from private company documents, an 'Invisible Admin' background worker simultaneously extracts their contact info, logs it into a Google Sheets CRM, and drafts a personalized follow-up in Gmail. This is a complete, scalable AI operating system designed to automate SDR work.
