🪪 About Me

As you may have guessed from the name of this website, my name’s Marco Cetica. I’m 25 years old and I live in Italy. This website is where I store my notes, guides and tutorials about computers and mathematics. I started it back when I was around 15, just taking my first steps into these two fascinating fields. Since then, it has connected me with people from all over the world: some got in touch just to ask a few questions or to point out a type while others turned into deeper conversations, a few of which are still ongoing today.

💼 What I do

I’m primarily interested in system administration and computer security, especially anything related to information security. I also have some practical experience developing programs, scripts and web applications across multiple technologies and languages; you can visit this page to see some of my personal projects. On the technical side, my skills are:

• 🛡 Computer security: data recovery, defensive security practices, network analysis and digital forensics;
• 💾 System administration: Linux, KVM, Docker, Kubernetes, Ansible, Bash, Python and Buildroot.

Beyond computers, I also have some grounding in applied mathematics, particularly the kind used to model real-world phenomena and to solve engineering/CS problems. That includes convex optimization, differential equations and the study of discrete structures such as graphs, integers and the like.
