A loyalty reward has two sides. A customer wants to redeem it at the till. A merchant needs to set up and run the offer.
Making redemption work
The work brought together the mobile redemption experience and merchant tooling. Low-latency lookups and offline-tolerant syncing supported the moments when a reward was actually being used.
The technical details matter because they show up directly in that interaction. A slow lookup or a difficult setup becomes part of the product for the person standing at the till or running the scheme.
