I am a software developer with a strong passion for open source software. On the Internet I use the nickname Smile4ever.

I was born on April 16, 1995 in Sint-Niklaas, a city in East Flanders (Belgium). At school, I studied applied computer science between September 2013 and June 2016. I use Manjaro Linux daily.

I can understand English, German, Dutch, French and Afrikaans.

Apart from my mother tongue Dutch, I also speak and/or understand English, French, German and Afrikaans. In use my free time, I like editing the Dutch Wikipedia (Smile4ever), writing software, combatting vandalism on LXDE Wiki, designing websites and listening to music.
