Senior Engineering Analyst & Technical Leader
Specializing in enterprise transformations, API migrations,
and high-performance system architecture
With over two decades of experience transforming complex technical challenges into scalable business solutions, I specialize in system migrations, performance optimization, and API-driven architectures for enterprises navigating digital transformation.
Currently leading critical infrastructure migrations at one of Australia's largest financial institutions (NAB), I bring deep expertise in Java, Spring Boot, microservices, and cloud technologies. My approach combines technical excellence with practical business value delivery.
Throughout my career, I've consistently delivered dramatic performance improvements—transforming processes from 20+ minutes to seconds, achieving 100x speed improvements, and building systems that handle millions of transactions reliably.
Over two decades of progressive technical leadership across financial services, sports technology, e-commerce, and telecommunications.
