I need a Fullstack developer to develop a custom server using Node.JS and PostgresSQL server. You will need to transfer Firebase back-end to the custom server. The server would be merged with an existing server running on Node.JS and backed up by the PostgresSQL server, to achieve a single custom server and a central database, deployable on any cloud server.
