Cloud Projects

01
Cloud Resume Challenge (This Website)

Full-stack serverless resume site. HTML/CSS deployed on S3 + CloudFront with HTTPS. Visitor counter backed by Lambda, API Gateway, and DynamoDB. CI/CD via GitHub Actions. The project that started it all.

S3 CloudFront Lambda DynamoDB Python GitHub Actions
02
PhotoBook Web App

A serverless photo album application where users can upload, organise, and view personal photo collections in the browser. Photos are stored in Amazon S3, with metadata (album names, upload dates, captions) persisted in DynamoDB. A Lambda-backed REST API handles uploads, retrieval, and deletion. CloudFront serves the static frontend and signed URLs ensure private photo access. The entire infrastructure is defined as code using AWS SAM and deployed automatically via GitHub Actions on every push.
