Customer KYC and Support App

I'm looking for a developer to create an app that allows my customers to upload KYC documents (ID Proof, Address Proof) and raise service tickets for product-related issues. The app requires background location access at all times.

Key features:
- Upload KYC documents (ID Proof, Address Proof)
- Service ticketing system for:
- Product malfunction
- Delivery issues
- Billing issues
- SMS verification for identity verification

Ideal skills and experience:
- Mobile app development (iOS and Android)
- Experience with document upload and verification systems
- Background location tracking integration
- Service ticketing system implementation
- Strong security protocols for sensitive data

Please provide examples of previous work related to KYC or support apps.
