Android developer + YOLO model integration + TFLite

I need an experienced android developer to build a simple android mobile app. With this app, the user as soon as he takes a picture of a specific object; my two-trained object detection model (based on YOLOv7) behind the scene will be invoked and they will produce bounding boxes & labels around that object. In the app, the final image will be shown and should also show the output as text below. I have models in .pt format as well as in .tflite format so if you are familiar with this type of integration, ping me.
The flow of model working is: input image -> first model invoked -> detect region of interest(roi) -> crop ped roi -> second model invoked -> detect objects
The complete code + apk should be delivered.
