Jan 2025 - Jun 2025

The Problem

Key Outcomes
- Custom Agent Builder with drag-and-drop workflow design
- RAG Knowledge Base for context-aware responses
- Agentic Booking System with Google Calendar integration
- Analytics Engine for call insights and performance metrics
- Multi-tenant architecture supporting 100+ concurrent calls
