# Ademar Reis > Director of Software Engineering at Red Hat, leading Azure Red Hat OpenShift. Twenty-five years on Linux, cloud infrastructure, and open source. ## Pages - [About](https://ademar.org/about/): I’m Ademar Reis, Director of Software Engineering at Red Hat, leading Azure Red Hat OpenShift (ARO), a first-party Azure service co-developed and co-operated with Microsoft. I’ve spent my career on Linux. I started in 2001 at a Linux distribution company in Brazil, and I’ve followed the platform up the stack ever since: from desktop and mobile systems, to the QtWebKit browser engine, to the KVM hypervisor at Red Hat, to the operating system underneath all of Amazon and AWS, and now to managed Kubernetes running in the cloud. Different layers, same substrate.
