Aspects of the disclosure relate to multicomputer processing of client device request data using a centralized event orchestrator and a link discovery engine. A computing platform may receive event definition information defining an event. Subsequently, the computing platform may receive a request for a recipient-selection user interface. The computing platform may mine alias data associated with a unique alias linked to a recipient computing device and may generate one or more relational user interface elements having relational content mined from the alias data. Then, the computing platform may send a delivery selection user interface having the one or more relational user interface elements to the recipient computing device. The computing platform may receive delivery selection information from the recipient computing device and may generate and send one or more event orchestration commands directing an event processor to execute one or more actions associated with the event.
