About

I design enterprise architecture that lines up business goals with the platforms, data and teams needed to reach them.

My work covers IT strategy, cloud migration across AWS, Azure and Google Cloud, GenAI solutions on Amazon Bedrock and leading LLMs, and the governance that keeps many teams moving in one direction. I have led TOGAF practices for UK clients, chaired architecture review boards and built reusable migration patterns that other teams still use.

Today I work on health plan implementations at HealthEdge, leading cloud infrastructure, cost governance, identity and observability across a portfolio of customer accounts.
