SecondServe — Give surplus food a second chance. Food can be wasted while nearby people and community organizations could use it. SecondServe is a neighborhood surplus coordination prototype: providers record a morning batch, sales reduce live stock, and remaining food can be offered free or at a discount. Neighbors browse nearby offers; rescue coordinators match surplus to eligible partners using hard constraints for capacity, timing, and handling. If a pickup falls through, the workflow releases the reservation and recalculates a replacement match. A pickup report only counts after a coordinator verifies the quantity. The demo shows one 20-piece simulated rescue using fictional Kadıköy businesses, recipients, map locations, and events. It is not a live marketplace: no real partners, point-of-sale integration, payments, pickups, or measured environmental savings are connected.
