Instant Auction House Car Bidding App

I'm seeking an experienced app developer to create a dynamic mobile application for my auction house business, which specializes in cars. This app should feature:

1. User Registration & Login: It is necessary to include functionality for users to register a personal account and login securely.

2. Car Listings: The app should host detailed listings of cars up for auction, with information and images.

3. Bid Tracking & Submission: It is essential for users to be able to submit and track their bids using a smooth and straightforward interface.

4. In-app Chat: Users should have the ability to chat or send messages to sellers directly within the app.

5. Payments: The app must allow users to seamlessly make payments for their bids via bank transfer.

Skills and experience needed:
- Proven experience in mobile app development
- eCommerce integration expertise
- User interface (UI) and user experience (UX) design skills
- Experience with payment gateway integration
- Excellent understanding of data security
- Bonus if you have developed an auction app before.

Looking forward to your bids. Thanks!
