/ ABOUT
I learn by taking things apart—then understanding why every piece worked.

I’m an IT student in the Netherlands focused on offensive security, penetration testing, and red teaming. I’m developing my capabilities through hands-on labs, self-study, and practical security challenges—with a clear goal: become a Penetration Tester.

My current work spans Hack The Box, VulnHub, Active Directory, and network security labs.
