A lot of people here recommend Flutter, React and similar. But these build upon frontend technologies and use a frontend mindset you might find very difficult to get into. If you know Java, I would instead recommend going through Googles new Kotlin courses for a week or so and see where that leads you: https://www.udacity.com/course/kotlin-bootcamp-for-programmers--ud9011 https://www.udacity.com/course/kotlin-bootcamp-for-programme... https://codelabs.developers.google.com/advanced-android-kotlin-training/ https://codelabs.developers.google.com/advanced-android-kotl... https://codelabs.developers.google.com/codelabs/kotlin-android-training-welcome/index.html#0 https://codelabs.developers.google.com/codelabs/kotlin-andro... Worst case, you have learned som kotlin which may eventually help you in your day job since kotlin is getting big in backend too.
