Help me with an AWS project you have worked on.
💡 Model Answer
I built a serverless e‑commerce catalog using AWS services. The front‑end is a static SPA hosted on S3 and distributed via CloudFront for low latency. API requests go through API Gateway, which triggers Lambda functions written in Python. These functions perform CRUD operations on a DynamoDB table that stores product metadata. For image uploads, users send signed URLs to S3, ensuring secure direct uploads. A separate Lambda processes image thumbnails and stores them back in S3.
To handle user authentication, I integrated Cognito User Pools, providing sign‑up, sign‑in, and MFA. The entire deployment is managed with AWS SAM (Serverless Application Model), which generates CloudFormation templates. CI/CD is set up with CodePipeline: code changes in GitHub trigger CodeBuild, run unit tests, and deploy the stack. Monitoring uses CloudWatch Logs and Metrics, with alerts for error rates. This architecture is cost‑effective, scales automatically, and requires minimal operational overhead, making it ideal for rapid MVP development.
