summary

Led a migration from a Java MVVM app using RxJava and Dagger to Kotlin over about four to five months, and the converter proves imperfect: in/out generics get wrong, automatic nullability creates nullable model fields that break APIs and DB schemas, and Java statics become companion objects instead of const val constants. Lessons: migrate models and abstractions first, then business logic, UI last; prefer Kotlin data classes and single‑expression functions; test framework compatibility (some libraries are not Kotlin‑friendly).
