We are looking for a Ruby on Rails Expert + React to Integrate Google Maps (Geocoding) and create a new feature.

We have a Ruby on Rails application. It's a transportation company.
Clients can book the transportation of the luggage on our website.
Currently we have a booking process. It was developed with Ruby + React.
The customer can enter an address and a travel date. It's now open, they can choose any date without restrictions.

The scope for this requirement is:

- Integrate google to choose the Pickup and delivery address on the form (created with react).
- Create planning: We want to create with google maps zones and the zones have a date/week where we are there. A country can to have more that one zone. A zone has many countries. (Check the example attached)

For the customer:
- When the user choose an address we need to check the zone and it shows the dates/weeks that we are traveling for that date.
- The user can choose only the dates planned for that zone.
