My name is Zhenis and I am a full stack developer with 5+ years of experience in mobile, web and game developing. I have experience in the development of iOS/iPadOS SwiftUI applications for storing categorized product ratings, which is exactly what you are looking for. My skills include fullstack development (Flutter, React-Native, React, Vue), online chatting/messaging app, GoogleMap / GPS App, photo/camera/video audio app as well as web service APIs (PHP / MySQL / JSON / XML).
I understand that you would like an iOS/iPadOS SwiftUI application for storing categorized product ratings with basic structure similar to the attached image and required features such as edit navigation option that permits item deletion or drag/drop between categories add (+) submenu with options for 'Category' or 'Product'. Category items have names and parent category (with implicit option of 'Top Level/Root') while product items have names, optional brands and boolean likeds. Image property uses PhotoPicker View to select photos at user's option if necessary while app respects Dark Mode options on device.
I look forward to hearing more about your project! Please feel free to
