About Me

As you may have guessed from the URL of this website, my name’s Marco Cetica. I’m 25 years old and I live in Italy. My area of expertise includes system administration with a focus on computer security, especially anything related to information security (such as data encryption, backup planning and data recovery), defensive security practices, digital forensics and network analysis.

Beyond technology, I also have a background in applied mathematics, which provides me endless reading material for my free time and a solid mental framework to tackle problems in a structured way. The areas of mathematics I like the most are combinatorics and operation research, in particular anything linked to (integer) linear programming and combinatorial optimization.

Although I don’t practice it as often anymore, especially since the advent of LLMs, I actually became interested in math and computers because of programming, which I first discovered back in 2011 or so, around the age of 11. During the years, I’ve tried a whole lot of languages, frameworks, paradigms and technologies. None of them ended up being my favorite but I guess the ones I can consider myself most proficient in are Bash, Python and C. Recently, I’ve also started exploring Clojure for building web services. Most of my projects are small scale tools and scripts I use to automatize repetitive tasks in my daily life. To learn more about my personal projects, visit this page.

Another great passion of mine is music, not just purposing it as a background noise while doing chores or running errands; rather, the act of actively focusing on a certain song/album by trying to grasp every single nuance of the track. I listen to a very heterogeneous set of genres which would be quite impractical to sum up in this section, I will probably write a dedicated post in the future about it if I ever would like to digress a bit about this topic.
