Career Summary

A results-driven Associate Product Director and Senior Solutions Architect with 25+ years delivering mission-critical healthcare technology across New Zealand, Canada, Australia, the United States, and Europe. Operating at the intersection of product strategy and technical delivery — from architecting provincial EHR and HIE solutions for federal and state governments, to leading production ML/AI platform initiatives on AWS at scale.

Recent work spans both AWS and Azure: on AWS, designing and delivering production ML/AI platforms in regulated healthcare environments — Databricks in customer-managed VPCs via PrivateLink, EKS-based model serving, vector stores, and LLM deployments, with robust observability, enterprise IAM, and DevOps practices — and most recently extending this to a multi-cloud footprint, architecting the Azure build of a regulated clinical NLP/AI search platform: a fully-private hub-and-spoke landing zone, Azure Databricks and AKS with GPU compute, provisioned as Terraform infrastructure-as-code and designed to meet Canadian healthcare data privacy requirements.

A recognised expert in Electronic Health Records (EHR) and Health Information Exchange (HIE), with deep expertise in ETL, integration, data modelling, and standardisation using AWS cloud technologies, microservices architecture, Kubernetes, CI/CD pipelines, and Agile methodologies. Strong focus on data privacy, security, and regulatory compliance including HIPAA and GDPR.

As a product and development manager, successfully conceptualized and built innovative applications, transforming them into commercial off-the-shelf products with a 'build once, serve many' model.
