About
I've spent nearly thirty years building software for UK financial services — wealth management platforms, in domains where the regulator eventually asks what you did and why.
I co-founded Wealth Dynamix in 2012 and spent six years as CTO while it grew to over one hundred people. Later I started Portemis, where I architected a new product that was eventually acquired by Wealth Dynamix. I rejoined as senior architect to take technical ownership of it — architecture, Azure, DevOps, reliability, observability and the messy cross-cutting problems that don't fit neatly into anyone else's box. Wealth Dynamix itself was later acquired by a major European investment bank in 2025.
Since July 2026 I've been building Cairn - https://cairnriver.io, an evidence layer for regulated work. It records what was done, why, and when, so a team can show the process they followed months or years later. Reviews, checks, approvals, exceptions — work where the record matters more than the artefact.

I'm happy to hear from people working in ai, compliance, operations, oversight, regulated financial services, or anywhere the process record matters. Equally happy to talk about anything on this site.
