# Week 2 – AI Digital Twin

I modificed the AI Digital Twin application to be a production-ready, full-stack  that represents **Joshua Balogun** in real-time conversations.
This project combines a modern Next.js frontend with a FastAPI backend powered by AWS Bedrock and deploys to AWS using Lambda + API Gateway + S3 + CloudFront + Terraform.
