Back to original languageAbout Aratz
I’m a security engineer and consultant based in Bilbao, focused on building secure, automated, and resilient infrastructures. My expertise spans security architecture, threat modeling, and cloud security in AWS and Azure, where I harden environments and align them with compliance.
I believe security should enable innovation, not slow it down. That’s why I take an automation-first approach—developing CI/CD pipelines, infrastructure as code (Terraform), and scripts that streamline testing and remediation.
I’m also exploring OpenStack and digital sovereignty, designing hybrid and on-premise setups that give organizations control over their infrastructure. Lately, I’ve been digging into AI compliance and monitoring, researching how governance and transparency can improve trust in AI systems.
Fluent in Spanish, English, and French, I enjoy turning complex security challenges into clear, practical solutions that help organizations stay both secure and agile.
