What I'm looking for

I'm looking to build high-quality, automated, cloud-based enterprise systems and APIs, while leading or collaborating with Agile teams across the full software delivery lifecycle.

I'm building cloud-based hospitality platform services at HRS Hospitality & Retail Systems, including Java/Spring Boot microservices, REST and GraphQL APIs, Stripe payments, POS configuration, and observability with OpenTelemetry and Grafana.

Previously at Virgin Australia, I delivered loyalty, baggage tracking, fraud prevention, airport operations, and token-migration services, including migrating 30+ microservices to support Keycloak and Ping JWT tokens. At Mastercard, AMP, JP Morgan, Zurich, and Allianz, I delivered payment gateway, financial advice, securities, insurance, pricing, and integration capabilities while improving performance, test execution, and delivery practices.

Across 24 years in software development, I've worked from requirements analysis through design, implementation, testing, deployment, and support. I lead teams in Waterfall and Agile environments and care deeply about quality, automation, maintainable systems, and practical outcomes.
