Corporate Vice President & Azure OneFleet Platform CTO at Microsoft
At Azure OneFleet Platform, my focus is the engineering behind Azure's global infrastructure: bringing capacity online, operating it reliably, and using it efficiently.
Open source has been part of the story from the start. I ran infrastructure for communities as an IRC operator in the OPN and freenode days, hacked on Gentoo as a student, took part in the first Google Summer of Code, contributed to OpenStack early on, and worked at GitHub.
My recent work spans cloud capacity and identity security. At Microsoft, I've led Azure Capacity and Foundational Observability: forecasting and delivering compute, GPU and storage across 50+ regions, bringing gigawatts of new capacity online each year.
Before that, I ran Entra Core Services in Microsoft Security, where the work combined identity systems processing trillions of requests each week with defence against persistent nation-state threats.
Earlier roles included Chief Information Security Officer at Oracle Cloud Infrastructure and leading EC2 Capacity, Forecasting & Placement at AWS — part of two decades in infrastructure that began in UK hosting and telecom.
On rebuilding my personal site, the ideas I threw away, and why the details matter.

Originally from the UK, now near Seattle. Building doesn't stop at work: a 1,000+ device Home Assistant setup keeps me busy at home.
We're hacking pipes, not just code — tackling projects at home and on the farm, and planning a space for fitness and wellbeing.
Fitness is a work in progress too — the ongoing battle against the bulge. Cycling helps; a love of good food keeps it interesting. There's also photography, reading, gaming, travel, and yelling at the TV during Kraken games. 🏒
