Looking for Nodjes and Reactjs Developer

Need to integrate facebook, messenger, line, viber, twitter, Skype and IMAP for our helpdesk that is built on react and node js. The main requirement is to make the integrations available for our customers companies, i.e. 1. If anyone posts on there facebook page the post gets saved in our database and a notification in the form of web notifications, system notification and email notification has to be sent. Likewise for twitter and other api's 2. If a new email arrived it should get saved on our database and then to be sent to all the other integrations in the form of notification. All this has to be done with node's child process so as to get a active thread always listening to all the users
