Logistics
Subscription grocery delivery with coupon ordering and driver routing
A daily-order platform where customers order products against coupons and drivers deliver the following day.
Client — a dairy delivery service
My role — Backend & API developer Team — 4 people
01 — Challenge
Daily delivery has a hard cut-off: an order placed after it belongs to the day after. The coupon balance has to be right at the moment of ordering, and the driver's list has to be settled before the round starts.
02 — Approach
Modelled coupon-based ordering against next-day fulfilment, so the day's orders close cleanly and each driver's delivery list resolves from them.
03 — Impact
Customers order daily products against coupon balances, and drivers get a settled delivery list for the following day.
