Build an Instant Message system in Firebase, ReactJS/Redux

I am building a dating app in ReactJS/Redux, Firebase and Bootstrap. The project is built on top of the following boiler point template: [login to view URL] The project is hosted in Github/Firebase. So the developer will need a Github and Google account to access. The backend for the user data is Firebase, which is a nosql database - so ideally the candidate will have working experience of Firebase. The work required is to build the instant messaging system part of the dating app with the following requirements: - Use redux to maintain state of instant message system - and dispatch actions etc. - When user 1 messages user 2, user 2 get's a notification. And user 1 receives read receipt if user 2 reads the message. - only user 1 and user 2 has access to these messages. - ability to read, delete, write and send messages. - Config option with a max number of messages a user can have. If this is reached a user will not be able to message and will receive a prompt stating this. The developer will be required to setup the views for this messaging system. However, no CSS work is required. Below are a few links which may help a developer before starting the project (including info of the message schema to use): [login to view URL] [login to view URL]
