Maintenance contract for React Native Mobile App (Arab Dev only)

I have an application developed using the React Native, the application is very similar to the “https://haraj.com.sa/” application in terms of its working mechanism.

Currently, the application is working and has not been launched. The application needs maintenance and modification to some of the application’s features or at the hosting level.

Required React Native language expert and proficient in working on Android and IOS version

The work will be for a long period, and therefore the offers submitted must be based on a monthly basis.

For example, the maintenance contract is for a period of one year, and the payment will be made monthly.
Due to difficulties with development, this project is for arabic speakers only)

The reason for changing the current developer is slow work, because modifications take from one to three weeks.

The application will not be reworked, so please do not submit offers to reprogram it
