About the maker
I'm a software development student (MBO) from Zuid-Holland.
At the moment I'm learning C# and working with APIs and JavaScript, and I'm interested in web development, UI/UX and Linux.
I've been putting code on GitHub since 2024: mostly small web apps, a Python network tool and a browser userscript. Away from the keyboard I'm usually hanging out with friends.
