Android developer kotlin

I am looking for an android kotlin developer to finalize an application
based on augmented reality and object recognition.
I propose a payment by module development.
my first need is to create an .obj object library that displays the objects from the database on the phone so that the user can choose an object and add it to the scene.
I use arcore sceneform for augmented reality and tensorflow lite for object recognition.
Would you be available and interested to collaborate?
