A quick commerce build across app, web and admin, covering ordering, rider assignment and live tracking.
What made it hard.
Stock accuracy per store decides whether the delivery promise is deliverable or a cancellation.
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.

Theirs, from day one.
Repositories, cloud accounts and documentation sat with the client throughout. Senior engineers wrote the production code rather than specifying it.
