John is our Master of Technologies. He is always exploring new frameworks and libraries, and is constantly extending his knowledge of code patterns and architecture. Most of our company's technical innovation is due to John's work.

Together with our system administrator Jeroen Dijt, he recently celebrated his 10th anniversary at Tritac. Together they have been the 'kernel' of our Tritac workforce for many years.

In his free time, John likes to keep his mind and body in shape through proper diet and exercise. You can't mess with him, as he's a fervent judoka and will put you on the floor before you know what's happening! He also loves to play darts, a board game or a card game. Together with the rest of our 'Team Healthy', he also takes part in several obstacle runs every year.
