Cross-Platform Document Scanning App

I'm looking for a mobile app that can scan documents and invoices with a phone's camera. The app should be compatible with both iOS and Android.

Key Features:
- Scanning: The app will use the phone's camera to scan documents and invoices.
- Categorization: Once scanned, the documents should be automatically sorted by the company name and the user who took the photo.
- Web Access: I need to be able to view these scanned documents from a PC via the web.

Ideal Skills and Experience:
- Proficient in cross-platform mobile app development
- Experience with document scanning app development
- Knowledge in categorization algorithms
- Web development skills for creating a viewing portal
- Strong understanding of iOS and Android systems
