Cleanup System Android App - repost

We are developing a cleanup system for Android and would like to hire a dedicated and committed professional for this job. Please find below the detailed information. The first step would be to implement the provided interface without any system functionalities, only design and flow. The app will need the following functionalities: - A junk file cleanup system organized by app that would allow the user to clean cache and residual files. -A privacy cleanup function that would allow the user to get rid of privacy information within the different installed apps. For example, It would allow the user to erase browser history from google chrome and search history from google play. -An app manager feature including an uninstaller as well as a way to backup the apk files to the device’s SD card. In a first approach, we would freelancers to implement a few screens of the app's interface, in order to select the most appropriate person.
