I’m looking for a developer to create a tool that enables authorized remote access to mobile device contact lists for data extraction and backup purposes. This tool should provide programmatic access to phone contacts and support both iOS and Android platforms while ensuring user data privacy and security. The solution will be used for business purposes, and I'm seeking detailed project proposals to bring this vision to life. While there’s no strict deadline for the project's completion, the design should prioritize functionality, compliance, and platform compatibility. If you've worked on similar projects or have insights into secure data handling and API integration for mobile devices, I’d love to see your approach.
