In an embodiment, a method is performed by a middleware computing platform and includes maintaining an active user pool comprising a plurality of servicing users. The method also includes exposing a service request interface to a plurality of user-to-user service platforms. The plurality of user-to-user platforms provide independent computing environments that separately execute user-to-user service workflows for requesting users. The method further includes receiving, via the service request interface, a plurality of service requests each from one of the plurality of user-to-user service platforms. In addition, the method includes automatically assigning one or more of the plurality of service requests to a target servicing user of the plurality of servicing users based at least in part on information associated with the service request and availability of the target servicing user. The method also includes exposing a service provider interface to the target servicing user. Furthermore, the method includes displaying, on the service provider interface, one or more service events respectively corresponding to the one or more assigned service requests.
