I have this particular hobby of creating applications that are useful, beautiful and fast. Backed up with my skills in React & React Native, I also unleash the power of native (Android/iOS) when necessary. You are right, my job the gym is my hobby.
In my free time, I write mobile applications and publish them.

Both my work and personal time involve open-source. I created several libraries such as react-native-sync-adapter and material-preferences. I also like to create useful examples such as react-native-testing-example. Furthermore I continuously contribute and/or maintain libraries I often use like react-native-viewpager, react-native-paper, jest and react-native.
I usually write on Medium. Some articles I am proud of are listed in the official documentation of Jest. They are about unit testing React Native apps: part 1 and part 2. I also wrote about the process of creating a native module React Native: The Android Sync Adapter as well as Android Drawer & StatusBar done right for React Native and React Native: Handling language changes on Android the right way. Finally, I also wrote the official announcement for the React Native Paper 1.0 release.
