Recipe Cost Sync and App Review

I need a skilled developer to integrate ingredient cost syncing into our existing recipe builder. Each recipe should automatically calculate its cost based on current pricing.

Additionally, I need a thorough review to ensure all functions are working and stable. This includes:
- Data entry
- Recipe saving
- Pricing updates
- Generating reports
- User access and permissions

Finally, I want to submit the app for review to both the Apple App Store and Google Play Store. Please confirm:
- The codebase meets all technical requirements
- All store assets (screenshots, descriptions, icons) are prepared
- Any required provisioning or developer account steps are handled

Ideal skills and experience:
- Experience with mobile app development on both iOS and Android
- Strong background in integrating APIs or syncing data
- Familiar with app store submission processes and requirements
- Attention to detail for thorough functionality testing
