    paper mood-melody app

    A showcase project demonstrating my end‑to‑end full stack development skills — covering architecture design, UI design, and both backend and frontend implementation, through to cloud deployment. Built with Next.js, React, Node.js (Express), and TypeScript in a PNPM monorepo, it leverages AWS Lambda, API Gateway, DynamoDB, S3, and AWS Comprehend for a fully serverless architecture and AI‑powered mood analysis. I also implemented a responsive frontend interface, optimized for both desktop and mobile.

    Both the frontend and backend are deployed on AWS Lambda, with automated CI/CD pipelines managed through GitHub Actions and AWS CodePipeline for seamless delivery and scalability.
