§ 01 / About

My career: from police software, to Google, to the UK's first digital census, to Admiral Money.

Varied technologies, a range of industries, and always with complex trade-offs.

I'm currently Chief Architect at Admiral Money, where I own the technology strategy for a £1.8bn consumer lending business.

I've also been driving adoption of AI tooling: from governed LLM access across the business, to agentic developer tooling with Claude Code, to early-stage experiments in contact-centre automation.

Aviation has sharpened how I think about engineering. Achieving my Sailplane Pilot Licence and working towards other endorsements has systems thinking and human factors. In safety-critical environments, clear checklists, unambiguous communication and disciplined decision-making are what keeps things from going wrong. I bring that same diligence to architecture decisions and incident response.

Outside of work you'll usually find me flying, travelling around in my camper van, tinkering with electronics, cooking, walking, or playing music (piano and guitar).

§ 02 / Featured work

2021 UK Digital-First Census - one huge event, every ten years.

The UK holds a census once a decade and 2021 was the first to be designed digital-first.

The challenge

The existing survey data collection platform was running on AWS. The architectural team had two mandates: prove that the system was cloud-portable by migrating it to Google Cloud Platform, and validate that it could handle the anticipated peak load - roughly one million households attempting to complete simultaneously on census day.

My role

I joined the ONS architecture team as a technical lead for the electronic questionnaire (eQ) application,. I subsequently moved into the Cloud Architecture team to work across software engineering, DevOps and architecture. I led the AWS-to-GCP cloud portability work, introducing Kubernetes-native deployments as part of the migration. I also designed the performance testing strategy — generating a million concurrent, realistic synthetic users is a non-trivial problem in itself, requiring careful modelling of submission behaviour and infrastructure headroom. This required close working with Google engineers to consider usage patterns that were beyond their usual planned levels.

The outcome

On 21 March 2021, the census launched and the digital collection system held. It handled a peak of 30,186 requests per second with 427,838 submissions during that peak hour. The groundwork laid during the architecture phase — cloud portability, Kubernetes orchestration, validated performance envelopes — proved robust under real-world load. It remains one of the largest public-sector digital delivery projects in UK government history.
