About

I've been building for others since 2010. Sears, Ferrari, Coca-Cola, Airbus, BBVA, Davivienda. Big names, real problems.

I show up when something doesn't scale, when nobody knows why it broke, or when the team has been doing the same work twice for months. I build clean interfaces, headless architectures, and proper infrastructure — and when I leave, your team owns it.

From CraftCMS and Statamic to Shopify Plus, HubSpot, Kubernetes and OpenBao I connect the stack end to end. Every decision I make has the next person in mind.
