Cloud Photo (https://github.com/JrTai/Cloud-Photo) is a face recognition single-page web application that I built entirely from front-end to back-end 2021. This web application lets users share and manage photos.

The whole project is completed in 5 Scrum Sprints, a total of 5 weeks. The server is deployed on AWS EC2 with AWS RDS as a database. Docker is used as virtual environments (image and container) with Jenkins CI/CD auto-deployment. Nginx is configured with Dockerfile to redirect clients from HTTP to HTTPS. The face album feature can classify people by Microsoft Azure face recognition service. The detected faces are saved to AWS S3 cloud storage. Mocha and Chai have implemented the unit tests.
