Mobile Claims Management App Development

I need a mobile application for managing claims, compatible with both iOS and Android. The app should connect with my existing structured SharePoint list containing relevant claims data, allowing users to submit new claims, view existing ones, and update claim statuses directly from the app.

Key Features:
- User-friendly Interface: The app needs to be intuitive and easy to use, optimized for both desktop and mobile devices.
- Data Integration: Seamless connection with a structured SharePoint list.
- Claim Management: Users should be able to submit new claims (via form submission and photo upload), view existing claims and update claim statuses. Essential fields include claim ID, description, date, responsible party, and claim status.
- Automation: Integrate with Power Automate for sending automated notifications.
- Reporting & Analytics: Smooth integration with Power BI for reporting and analytics.

Ideal skills and experience for the job include:
- Mobile app development (both iOS and Android)
-power App
- Experience with SharePoint and Power Automate
- UI/UX design for mobile applications
- Knowledge of integrating with Power BI for analytics
- Proficiency in implementing form submissions and photo uploads within an app.

I am looking for your thoughts and suggestions on the best implementation strategy.
