Senior Full-Stack Engineer & Former CTO

Fifteen years building production software.

From enterprise (PwC) to high-growth London startups (Movebubble, Just Insurance, Hostology) to founding-CTO roles and my own engineering studio. I architect and ship full platforms end to end — product, infrastructure, code, deployment, and the AI layer on top. Real teams, real products, in production.

The Daily Magazine

An editorial that compiles itself

A full magazine — the world, power, AI and the spirit — that builds itself overnight: ~30 sources fetched, classified, and written into long-form features by Claude Opus, then laid out as a paged magazine with its own colored spread per section. Taste, an AI pipeline, and automation in one running piece.
