FAQ
Will migration break my existing features?
I run a full regression check after migration to confirm nothing broke. If anything needs adjusting, that's covered in the revision rounds.
Do you handle both Android and iOS build configs?
Yes — Gradle (Android) and Xcode/Podfile (iOS) are both updated as part of every migration.
