AM LOOKING FOR A HUMAN EXPERT SOLUTIONS.

have written this smartcontract for a decentralized rideshare appli cation.

This app will serve as a catuall ridesharing app for pople to make extra cash while they are heading to thier preffered destination $($ such as soemone who uses his$/$ger car can pick$/$drop someone on thier way to$/$from work or any place they wish to go$.$

This application is a ridesharing just like uber, but it will be similar to some social media platforms such as Facebook. This featres makes it smillart to facebook;

$1,$ the users $($ both driver and rider$)$ will register, sign in$,$ and send and aceepts friend requests from other.

$2.$ Driver can post the ride to general public or just friends that tells he$/$she is going from point A to B$.$

$3.$ Rider can also post a ride request both to general public or just friends that looking for ride from point A to B$.$

$4.$ both parties will have the access to messaging section each other in private.

So please write a script to deploy and test it in Remix etherum and a full backend$/$ SPDX$-$License$-$Identifier: MIT
