About

I'm a Senior Cloud DevOps Engineer at the Holcim EMEA Digital Center in Madrid, where I've spent the last three years building and automating AWS platforms with Terraform and GitOps.

Before that I worked as a cloud engineer at Deloitte for Santander Consumer Finance, and started out administering a payments platform at Accenture for BBVA — over five years working on infrastructure for large regulated organisations. I studied at the Universidad Politécnica de Madrid.
