Millions of customers and billions of points: a new rewards currency in the cloud

The project began by migrating the members and points from a longstanding loyalty programme used in another of the group’s companies, from an established but expensive, inflexible, and opaque platform to new AWS-based infrastructure. This element alone would represent a considerable cost saving as well as a dramatic improvement in performance and unlocking new data mining opportunities.

With the new infrastructure in place, we developed an API to enable rewards spending across partner companies and within the group. We added monitoring and detailed financial reporting on the new system’s transactions sufficient to satisfy external financial auditors, with a security environment consistent with banking sector best practices.

The work was carried out by an Infinity Works full stack squad working within a wider team, along with Infinity Works delivery and architecture leadership, and providing out-of-hours support.

In 12 months and with a team of six consultants, Infinity Works:

built a brand new, greenfield loyalty platform running on AWS, with automated testing and a CI/CD pipeline, enabling rapid feature roll-out and new partner onboarding;
implemented monitoring and alerting, enabling fast response times and ensuring that the system remains trusted, reliable, and loved by the customers;
migrated legacy data and transactions intact, and providing better accessibility to customer history, enabling data mining, cross-company recommendations, and more;
upskilled the customer’s own technical leadership in DevOps best practices, growing a capability within their business;
built a suite of APIs, an onboarding process, and a billing platform allowing any group company or partner to plug in to the rewards platform with minimal effort.
