• Shifted a 1,500+ quality engineering workforce from semi-automated testing to engineering-first, shift-left automation, enabling continuous delivery and ST/ST+1 execution with less rework.
• Established a quality dashboard surfacing testing hotspots, lifting coverage to 90% on hotspots and 100% on all P1 cases.
• Moved platform engineering from tickets to self-service: 10+ asset teams now provision, deploy and manage infrastructure themselves, eliminating hundreds of support tickets; rollout to major assets underway.
• Cut external contractor reliance by 70% through in-house capability build-out, backed by a cross-location workforce review, a new engineering operating model and hiring roadmap.
• Chaired the Group CEO's NAB Vietnam Initiative (FY25–26), a company-wide hiring-quality and culture-fit programme spanning all levels.

• Defined platform architecture for the CIBG Entitlement Management System, with a target design reusable by RBG and GTS.
• Established the bank-wide CIAM and identity & access reference architecture with Enterprise Security, reducing design variance across domains; served on the Design Approval Board.

• Partnered with Mastercard to deliver the Pacific region's first Tap-on-Phone payment solution on scheme-direct gateways; onboarded 50+ merchants and opened a new revenue line.
• Built an end-to-end cloud Loan Origination System for a New Zealand non-bank mortgage lender.
• Owned engineering strategy, architecture, cloud cost, budget and AWS / Azure / MongoDB partnerships.
• Built the engineering capability from the ground up, with weekly releases on a fully automated, fully tested CI/CD pipeline from day one.

• Productised a SaaS digital marketing platform on AWS from proof of concept to production, with a high-performance batch-processing pipeline; built the in-house engineering team.
• Delivered a GDPR compliance programme, operational analytics and a full disaster recovery plan.

• Led two agile squads (20+) and an offshore support team across time zones for a human capital SaaS platform used by Fortune 500 clients.
• Improved platform throughput 20x by re-architecting a monolithic .NET application on Azure into AWS-native microservices; led the Azure-to-AWS migration.
• Moved from release trains to continuous delivery (weeks to days to production), raising test coverage from 10% to 75–80%.
• Moved siloed products onto one platform architecture; permanent member of the Architecture Guild, setting long-term technical direction.
• Turned around an underperforming team through 1:1 coaching, restoring velocity and morale.
