Live coding converts a React Native mock-recipe app into a cloud-connected app using TypeScript and AWS Amplify: adds Cognito-style authentication, DynamoDB-style data models with type-safe generated clients, S3 file storage with pause/resume uploads, and Amazon Bedrock-backed generative AI for ingredient parsing. The presenter scaffolds infrastructure with the Amplify CLI, deploys backend.ts configuration, replaces mock repositories with real model create/read/update/delete calls, and demos uploading a photo and auto-extracting ingredients — all working end-to-end.
