Carlos Jeurissen

I’m an independent software developer from the Netherlands. Aside from working on several browser extensions, I do a lot of freelance work in collaboration with Papermill.


Papermill Collective is a group of freelancers specializing in Material Design. As co-founder, I help form project-based teams to create websites, apps or browser extensions from our global network of designers, developers, illustrators and animators.


I started Playsprout Industries with Michael Cook. At Playsprout, we craft beautiful, engaging, educational apps that cultivate creativity without being over stimulating or deceptively monetized.
