About me

I'm a System Administrator with over three years of hands-on experience in IT infrastructure and cybersecurity.

I like to understand how systems work, troubleshooting problems and finding practical ways to make infrastructure more reliable, secure and easier to manage. I'm particularly interested in Linux, virtualization, automation and infrastructure security.

I learn best through practical experience. Outside of work, I spend time experimenting with new technologies, working on personal projects and practicing cybersecurity through CTFs and self-study.
