Welcome on the site of Geoffrey De Belie! I was born on April 16, 1995. I live in Belgium, in a town called Sint-Niklaas.

At school, I studied applied computer science. I'm often online on Wikipedia and IRC (Freenode), where I have my own chatroom. I can understand English, German, Dutch, French and Afrikaans.


I made some websites, using HTML 5, CSS 3 and PHP: I have experience with PhpBB as well.


I created and adapted some computer applications. I know C#, Visual Basic, Java and Gambas well. Examples: Check out my GitHub-profile: Smile4ever

Firefox extensions

Firefox extensions are made using XUL (optionally) and JavaScript.
