I have just a few experience with React Native(no production code, no video record, even no blog). But I will try some thing in next month(Doing a self challenge recently, one coding video per day, will start React-native part soon).
Look forward to your more blog about Xamarin :)
Because I think engineer should choose the best tool, not just stick to one language, one framework, etc.
If I find out Xamarin is better in the future, gonna try it out for sure.
