Iago Alonso

Systems and Platform Engineer

About

I’m a systems and platform engineer with a background in software development and experience operating large-scale production infrastructure.

I work across Linux, Kubernetes, networking, distributed databases, infrastructure automation, and observability. My role combines systems engineering with platform and site reliability work, including designing and operating production services, improving reliability, and automating operational processes.

My software development background influences how I approach infrastructure: systems should be reproducible, observable, maintainable, and safe to operate.
