Description

🚀 Infrastructure & Platform Engineer

I have been helping companies design, secure, and industrialize their cloud and hybrid infrastructures for over 10 years.

Specializing in multi-account AWS environments, Kubernetes, and cloud + on-premise architectures, I design robust, scalable, and cost-controlled platforms, suitable for critical environments (health, media, SaaS).
