NPO is my full-time employer. At NPO I am a web developer and part of the player team where we develop media players. My focus is on the video and audio players for the various NPO platforms including NPO Start and NPO Luister as well as the websites for the NPO Radio channels and independent broadcasters under the NPO Umbrella.

In my spare time I do volunteer work on the HDOS OldSchool RuneScape client project. This project is aimed at re-creating the 2008-2011 era RuneScape HD look for OldSchool RuneScape through a reverse engineered client dating back to 2009. On the project my primary focus is porting over RuneLite plugins and making them compatible with our client. Though I have also delivered core client features and contributed art assets and tooling that boosts our artist productivity.
