It's a complicated overlap between platform specific versus React Native knowledge, will be hard for RN docs to cover all the platform specific stuff.

Profile the APK natively. Add <profileable android:shell="true" /> to your AndroidManifest then do a native profiling of your APK via Android Studio. Then edit the build configuration to start profile recording on startup.

This could be many things. If the scroll is choppy at the native level maybe the UI thread is too busy. Few tips, only do this with a release build:

Micromanaging is a big part for sure. But I also think that not everyone is fit for remote work. It takes high level of self agency to be productive in a such a free environment and to find such talent takes a bit of hit and miss.
