I am one of the co-founders of www.livetrips.gr. This is a platform since 2008 where travellers around the world post information while travelling. We would like to upgrade our 2 mobile apps on Android and Apple to a newer version. I am the leading developer on both apps but I have stopped working on both of them in the last 2 years. The Android one was build using Java and the iOS one using Objective-C. You will not find the iOS app on the store any more, so please go ahead and download our Android app (search for livetrips)
The app is using Drupal APIs to send information to our platform which is a Drupal site :)
What we want is: 1. To build ONE mobile app using the latest Cross-platform development frameworks such as React-Native (preferred) with the same functionality as it is now. 2. What will be the cost to build it 3. An estimation on the deadline
Access to the code will be provided in order to see the calls to the endpoints and other relevant information you might need. All the functionality will be given and an NDA will be signed!
