Technical Implementation

Built with Flutter and Firebase for a scalable, real-time rental platform:

• Firebase Authentication for secure user accounts
• Firestore for real-time database operations and availability tracking
• Cloud Storage for car images and documents
• Push notifications for booking updates and reminders
• Complex date/time handling for rental periods and availability checks

Challenges & Solutions

Managing real-time availability across multiple concurrent users required implementing Firestore transactions and optimistic concurrency control to prevent booking conflicts.

Designing an intuitive date picker for rental periods while showing real-time availability was solved through a custom calendar widget with visual availability indicators.
