My journey

My name is Calogero Lo Leggio. I was born in 1985 and live in Perugia, where I moved at the age of twelve from a small town in inland Sicily.

Computing entered my life early, with the Amiga 1200 my father brought home. What began as a purely technical interest took on a deeper meaning when I discovered Free Software and its underlying idea: technical knowledge is not property to be defended, but a common good to be shared.

That encounter led to the hacklab I helped found in Perugia, the courses I taught and my work translating technical documentation. Sharing has remained the common thread throughout my journey, both in and outside work.

Since 2000, I have been exploring the administration of UNIX-like systems—particularly GNU/Linux, OpenBSD and FreeBSD—and the areas surrounding them: security, virtualisation, clustering and high availability. Over the years, I have followed the evolution of the industry through automation, Infrastructure as Code, containers, orchestration, GitOps and observability.

I began my professional career in 2007 in the ISP sector, first at Teleunit and then at OKcom, working on enterprise systems, configuration management and early private-cloud experiments. I later designed a cloud-based HPC platform for genomic computation.

In 2010, I founded LibreIT, through which I design and manage cloud, on-premises and Kubernetes infrastructure for Italian companies. Many of these collaborations have continued for more than ten years.

Since 2015, I have also been IT Manager at Desegno S.r.l., where I led the transition from infrastructure administered manually, one server at a time, to an environment described entirely as code: virtual machines, containers, Kubernetes orchestration, and versioned, reproducible configuration.

I try to share what I learn by teaching courses on Linux, containers and Kubernetes, helping maintain several Debian packages and writing technical articles. I also take every useful opportunity to speak about Free Software and Open Source. I am currently shaping a new training project dedicated to system engineering.

Away from the keyboard, there are travels, trekking, concerts, science-fiction books and arthouse films, together with the desire to keep learning something new—which, sooner or later, almost always brings me back to the keyboard.
