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

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

Apart from my mother tongue Dutch, I also speak and/or understand English, French, German and Afrikaans and in lesser extent also Spanish and Esperanto. In my free time, I like editing the Dutch Wikipedia (Smile4ever), writing software, designing websites and listening to music.

I made some websites, using HTML 5, CSS 3, JavaScript and PHP:


I created and adapted some computer applications. I know C#, Visual Basic, Java and Gambas well. Examples:
  • VLC Lyrics Finder (multiplatform), get lyrics for the current song in VLC Media Player
  • ChatZilla for #hugsmile (for Windows), an user friendly version of ChatZilla Portable (adapted binary version)
  • WikiList (for Linux) - generates and filters MediaWiki lists from LinkSearch and WhatLinksHere results. Lists can be saved for import in AutoWikiBrowser. (Gambas)
  • Text2SRT (for Linux) - subtitle music videos and movies (Gambas)
  • LyricsCore - a lyrics API (PHP)
  • subconv - convert subtitle formats (JavaScript)
