Test my mobile app for the react native

I am looking for someone to write unit tests for the react-native mobile app. The app is written in js and tests need to be written using jest. I am looking for quality test code rather than just covering maximum lines. Actually, there are three different variants of the apps. Please check the demo videos at the below link. The apps have many other features than what is shown in the videos. I will share more details with the interested candidates.
