To build Delunico Drive, I developed a React web application that enables users to store, download and share their files through a Firebase API. The app incorporates several technologies such as ReactJS, Node.js, Bootstrap, and Firebase, with data being hosted on Google Firebase and accessed via its API. User authentication and password recovery features are included, with the option for sharing download and viewing links to their files. For user data protection, the app incorporates HTTPS SSL certificates, encryption of passwords using a hash algorithm, and authorization controls to prevent unauthorized access to other user's files. The front-end is now deployed on railway.app, while the project was formerly hosted on the Heroku web server. The application utilizes the MVC design pattern, RESTful service layer, and Single Page Application (SPA) with CRUD functionalities that allow users to upload, create directories and subdirectories, and update their account information.
