Hello, World!

BIO/ INTRO

I build the products and platforms that millions of people rely on — without ever noticing. Identity, fulfilment, personalisation — at the scale where the stakes are real and the complexity is unforgiving.

Eighteen years across six FTSE 100s and three Global 500s. Currently leading Tesco's identity platform — serving tens of millions of customer accounts across five markets. Previously: Sky, Barclays, Vodafone, Fidelity International, Telefónica, Department for International Trade.

I deliver the things others say can never be done.

Author of Product Truths: Five Principles for Building Products That Work at Scale. I write and speak on identity, platform, and AI — most recently at CX in Financial Services — because the best operators should be able to explain what they build, not just build it.
