Prolific cross-platform mobile dev — Flutter + native iOS/Android
assessed from open-source footprint
Joel is the deepest mobile specialist here: 57 original repos over 14 years spanning Dart/Flutter plus native Swift, Kotlin and Java, with projects like a Flutter+native 'Ultra Mobile' challenge and an artisan e-commerce app for the DR. The caveat is maintenance — a 77% abandonment ratio and only 4 stars total mean lots of exploration over polished, starred products. For a team needing genuine cross-platform (Flutter + native) breadth, his range is the standout asset.
