Developed few native libraries for React Native: entire camera with possibility to draw on images (in 2017 not many libraries was for that), library for recording phone calls and calls history.
I have experience with optimizing applications on React Native. Once I had overloaded list, where items had images, many texts, when user scrolled this list - FPS was 15-20 even on IPhone. I used lib to optimize this list, but also have to write some utilities to indicate heights of each items because each items had different height - and this was a problem.
