Car Auction Management App

I'm looking to develop a mobile app specifically designed for car dealers to manage auctions. The app should include:

- Inventory Management: Car dealers need to easily add, view, and manage their auction cars.
- Live Auction Support: Real-time bidding capabilities, with notifications and updates.
- Payment Processing: Secure payment transactions within the app.

Ideal Skills and Experience:
- Mobile app development (iOS and Android)
- Experience with real-time data synchronization
- Strong knowledge in secure payment integration
- Background in developing inventory management systems
- UI/UX design skills for a user-friendly experience

Please provide examples of similar work done.
