Mobile Applications Engineer with about 6 years of native Android development experience. Also worked with Flutter and React Native. Though I can't say cross-platform frameworks are exactly my cup of tea but in general, I believe that development is not about frameworks but more about the state of mind, because a good developer should be able to deal with any adequate framework or even programming language if they have a need to use it in some projects. So, I try to develop a spacious mind and to know more about development in general, its quirks and odds. Personal preference is still mobile development because you can work on something...
