about me
I am Marc, a cybersecurity student in my second year at IPSSI based in Paris. I work part-time as a Linux engineer for a company in the Czech Republic, where I handle server administration and infrastructure security across virtualized environments. That is my day-to-day, but the broader goal is to build a solid career in cybersecurity, whether that ends up being on the defensive or offensive side.
My interest in security did not start in a classroom. It started with the kind of curiosity that makes you strip a Windows installation down to its bare essentials, removing telemetry, disabling bloat, building a custom ISO from a Windows 11 LTSC IoT base just to see how clean and controlled a system can actually be. The same mindset led me to Arch Linux, which I run and maintain not because it is trendy, but because it forces you to understand every layer of what is running on your machine. I genuinely enjoy the process of hardening and optimizing systems, reading documentation, testing configurations, and making things work properly. Performance tuning and resource allocation are another side of that same obsession. Getting a system to do more with less, squeezing out unnecessary overhead, knowing exactly where every cycle and every megabyte is going, that is the kind of problem I find deeply satisfying.
Helping people in my class is also part of how I learn. It pushes me to go further, to articulate concepts that feel obvious to me but are not necessarily clear to others. Having to break something down and explain it properly is one of the best ways to actually verify that you understand it yourself.
Outside of screens, I train regularly. Calisthenics, rock climbing, and Muay Thai. I cook often, I love cinema, and I listen to a lot of music. I have also had the chance to travel a fair amount for my age. Thailand, Canada, England, Laos, Myanmar, Spain, Italy, Switzerland, the Czech Republic, Croatia. It opened me up to other cultures and other ways of functioning, and it enriched how I see things.
