Project 2Completed

Secure Cloud Photo Sharing Website

Developed a ReactJS Single Page Application (SPA) integrated with a FastAPI backend via Nginx Reverse Proxy. Managed the JWT authentication lifecycle in the browser, securely attaching Access Tokens to Authorization headers to protect user resources.

Integrated AWS CloudFront RSA-2048 Signed URLs (60s TTL) for secure, ephemeral image rendering from private S3 buckets. Containerized the frontend using Docker & Nginx, configured internal bridge networks, and assisted in AWS EC2 deployment.
