Background
I'm Marcin Czaja, the designer and developer behind RoseaThemes.
I started working with Moodle almost by accident. At first, building themes was just a side project alongside my regular web design and development work. Over time, more people started using them, the projects became bigger, and eventually RoseaThemes became my full-time business.
The name Rosea comes from the Latin word for “rose-colored.” I liked the idea behind it — looking at things from a more optimistic angle — and the name stayed.
What kept me interested in Moodle was that I wasn't just designing another marketing website. These are interfaces people actually use every day to study, teach and manage courses.
Today, most of my work is focused on what happens after a site goes live: keeping themes fast, accessible and easy to maintain. I care about things like keyboard navigation, clear interfaces, sensible settings and making sure an admin can change something months later without having to rebuild half the site.
