Overview

Grocery delivery with rider dispatch and live tracking, engineered for sub-ten-minute promises.

01 — The challenge

What made it hard.

A short delivery window requires store-level inventory accuracy, forecast rider supply and dispatch decisions made in seconds, all holding at once. Any one of them failing cancels the order.

Rider supply

Demand spikes in twenty-minute windows. Supply has to be forecast, not reacted to.

Slot honesty

Showing a delivery window you cannot meet costs more than showing a longer one.

Unit economics

Every extra minute and every failed drop is measurable margin.

02 — The product

What we shipped.

Customer ordering and live tracking, a rider app with assignment and proof of delivery, dark store picking tools, and operations dashboards per store.

03 — The build

How it holds up.

Dispatch was built as its own service with replay tooling, so any assignment decision can be audited after the fact rather than argued about.

The system
Store-level inventory is the source of truth and the product refuses to display a delivery slot the system cannot back. Location data passes through smoothing before it reaches a customer-facing map.
