🛠️ Tech Stack & Architecture

Frontend:

• React.js: Component-based architecture for seamless state management.
• HTML5-QRCode: For browser-based camera access and QR decoding.
• CSS3: Custom responsive design.

Backend (Serverless):

• Firebase Firestore: NoSQL database using Snapshot Listeners for real-time data sync across client devices.
• Firebase Authentication: Secure login for admin personnel.
• Firebase Hosting: Fast content delivery.

Why the Reads were so high (1.2M)? The app utilized aggressive real-time listeners. Every time a schedule change occurred or an alert was pushed, every connected client updated instantly without refreshing the page, ensuring delegates never saw outdated info.
