The project is a robust and scalable push notification system developed using Node.js. The system is designed to efficiently handle a high volume of push notifications. It leverages the asynchronous nature of Node.js, making it perfectly suited to manage operations that might block the server, like sending push notifications to thousands or even millions of users. The system can be used by applications to inform their users about various updates, alerts, or any significant information. It provides a way to engage users actively, even when they are not currently using the application

• built complete front-end and back-end from scratch;
• authored and executed OpenAPI specs for API interoperability;
• integrated with Apple's APNs and Google's FCM for cross-platform notifications;
• developed a unique scheduling feature for optimal notification times;
• deployed on Google Cloud with an auto-scalability strategy for dynamic traffic management;
• performed comprehensive system testing and containerized the system using Docker;
• implemented secure authentication protocols to ensure only authorized entities have access to certain resources, thereby enhancing system security;
• established rate-limiting rules to prevent abuse of the API endpoints, ensuring stability and availability of the system even during high-traffic periods

The app allows users to participate in live auctions from the comfort of their own devices. Users can browse and bid on various items presented in the live stream, with the ability to see the current highest bid and place their own bid in real-time. The app also includes user authentication, allowing users to create an account and sign in to participate in auctions. In addition, the app includes a chat feature, allowing users to ask questions and communicate with the auctioneer and other participants during the live stream. Overall, this project provides a convenient and immersive way for users to participate in live auctions and bid on items they are interested in.
