What I'm looking for

I'm seeking senior engineering roles building secure, cloud-native platforms (FinTech/Health) where I can lead and mentor, deliver scalable compliant systems, and apply AI/ML and modern cloud/DevOps practices.

I am a Senior Software Engineer with over 12 years' experience building secure, high-performance platforms across financial services, healthcare, and e-commerce using Python, Node.js, Java and modern JavaScript frameworks.

At Stockspot I led end-to-end development of savings and investment features, re-architected backend transaction services, integrated Open Banking and BPAY, and introduced AI/ML-driven goal tracking while migrating workloads to AWS with Terraform and CI/CD.

I focus on designing compliant, scalable systems—applying PCI-DSS, AUSTRAC and OWASP best practices—mentoring engineers and collaborating with product and compliance teams to deliver measurable performance and security improvements.
