Mobile app and website for travelers

I am looking for a mobile app and website that caters to the needs of travelers. The ideal candidate should be able to develop the app for both iOS and Android platforms.

I have specific features in mind for the app and website and would like the ideal candidate to be able to incorporate them.

Social media integration is a priority feature for the mobile app and website. Users should be able to integrate their social media profiles seamlessly.

The ideal candidate should be well-versed in user registration and profiles, as well as booking and payment systems.
