Interactive Real-Time Coverage Map Development

I need a tech-savvy freelancer to build an interactive real-time coverage map with integrated backend. The ideal candidate should be handy with Google Maps and Google Earth as addresses are intended to be sourced via Google lookup, alongside an option for adding manual addresses.

Key functionalities needed include:
- Real-time updating of coverage status: The map must display live status changes for each address.
- Filtering options: The map should effectively filter addresses based on their various statuses such as “live” or “pre-order”.
- Google Maps and Google Earth integration: Addresses should be easily importable from these platforms.

When an address is added manually, a prompt for user confirmation of the address details is required for accuracy. Each address displayed on the map should reveal specific details, including the street, city, state, and zipcode.

Skills and Experience:
- Proficiency in programming languages commonly used for backend and map development
- Familiarity with real-time data integration
- Previous work experience with Google Maps and Google Earth integration
- Detail-oriented with emphasis on accuracy of address information.
