Christian MacMillan
Born in Mallorca, I’ve always been interested in both design and technology. While studying Computer Engineering, I found myself drawn to more creative ways of building software, particularly through motion, interaction, and visual experiences.
That interest took me to Madrid and later Barcelona, where I spent six years working at agencies like Vasava and B-Reel on projects for brands including Google, Nike, and Netflix.
In 2020, I started working independently. What began as a freelance practice has gradually evolved into a small studio, collaborating with developers, designers, copywriters, and other specialists depending on each project.
Above all, I try to make collaboration easy. Clear communication, asking the right questions, and being open throughout the process are just as important as the work itself.
