🚀 Strong Points & Technical Excellence

This project is built with modern software engineering best practices, ensuring scalability, maintainability, and a premium user experience:

• Modern Stack: Built on the powerful combination of Next.js (Frontend) and NestJS (Backend), providing a robust, server-rendered, and API-first architecture.
• Type Safety: End-to-end TypeScript implementation ensures fewer runtime errors and an excellent developer experience.
• State-of-the-Art AI Integration: Leverages Vapi AI for seamless voice interactions and OpenAI for intelligent response evaluation and topic extraction.
• Robust Database Architecture: Uses Prisma ORM for type-safe database queries and schema management.
• High-Performance UI: Beautiful, responsive interfaces built with Tailwind CSS v4, enriched with fluid animations using Framer Motion and Lottie, and optimized data fetching via React Query.
• Enterprise Security: Secure authentication flows utilizing Next-Auth and JWT (JSON Web Tokens).
• Containerized Deployment: Fully dockerized frontend and backend with docker and docker-compose support for consistent environments across development and production.
