As a junior developer, Cas is part of the development team and together with his fellow programmers they make sure that cool and high quality solutions are made. In the team, Cas is mainly involved in programming the slightly less visible elements of the codebase. With his mathematical approach, he hopes to lead both the customer and his colleagues to new insights. If he is not puzzling over a code, he does so in his spare time. Puzzle games on his phone and putting together complicated contraptions in games like Minecraft and Factorio keep him busy. Cas also does bouldering and relaxes by reading while on a walk.
