Context
Following NAB's acquisition of Citigroup's Australian consumer business, Project EDGE sat inside a $1.6 billion multi-year technology transformation — replacing legacy infrastructure and overhauling credit card and merchant platforms. The program needed a safe way to prove the new mobile stack before migrating multiple Citi whitelabel brands.
Challenge
NAB could not afford to rebuild multiple partner-facing credit card apps on unproven foundations. The delivery model had to validate platform capabilities on a controlled internal pilot, then support distinct whitelabel brands from a shared multi-tenant platform — with reliability, predictable releases, and clear engineering standards.
Approach
Delivery started with an internal pilot — the NAB Edge Credit Card for staff — to prove key technology features in production. Once the platform was validated, the same micro-frontend architecture powered whitelabel delivery across multiple partner credit card apps, with cross-team alignment and pragmatic platform leadership throughout.
Impact
The pilot-to-scale model migrated more than 1 million Citi whitelabel customers to NAB and established a reusable mobile platform inside NAB's broader $1.6 billion technology transformation — reducing delivery risk and proving the stack on a real NAB-owned credit card product first.
Pilot-first platform delivery
Before scaling to partner brands, Project EDGE validated key technology capabilities through an internal staff pilot — the NAB Edge Credit Card. This followed a product operating model mindset: prove outcomes on a real production surface, learn fast, then expand the shared platform with confidence.
Internal staff pilot
The NAB Edge Credit Card was built and released as a staff pilot — a live credit card product used to exercise the new mobile platform in production before whitelabel migration.
Prove, then scale
Core capabilities — onboarding, account management, digital card, payments, and release discipline — were proven on the pilot before rolling the same micro-frontend foundation out to multiple partner-branded credit card apps.
Outcomes over output
The pilot de-risked a 1M+ customer migration by prioritising validated platform outcomes over shipping features on a fixed roadmap — aligned with empowered, cross-functional product team delivery.

NAB Edge Credit Card
The NAB Edge Credit Card was NAB's internal proof point for Project EDGE — a real credit card on a new React Native stack, delivered by a cross-functional team using Progressive Elaboration and a phased staff rollout before the same platform scaled to whitelabel migration.
Partner credit card apps on the shared platform
After the staff pilot, the same multi-tenant React & React Native micro-frontend foundation powered multiple partner-branded credit card apps across retail, airline, and consumer finance — each with distinct branding and customer journeys on shared core banking capabilities.
