Banker Platform Revitalisation & Citi Integration at NAB
Led the architecture direction and technical strategy for a major modernisation effort within NAB's banker platform — moving a legacy monolith toward a modular, white-label–capable architecture, alongside the Citi acquisition integration.
Challenge
Modernising a legacy banker monolith into a modular, white-label–capable platform while meeting the Citi acquisition's regulatory timeline — without disrupting live banking services.
Solution
Owned the architecture and technical direction for the teams I led, shaping the shift from a monolith to a modular, independently deployable architecture and aligning delivery across the combined NAB and Citi teams.
Outcomes
Set the architecture direction for a high-stakes modernisation and acquisition program
Delivered against the Citi acquisition's regulatory timeline
Established modular, white-label foundations for the platform
