About me

Biography

I'm Julián Camilo Rueda Ramírez, a Colombian UX/UI designer and front-end developer. For over seven years I've designed digital products for companies in education, technology, retail and telecommunications.

My work brings together three things: research with real people, design systems that scale, and the technical judgment to take an interface all the way into code. I care especially about accessibility and culturally purposeful design.

I'm the author of the book Mundo U'wa, published by Editorial USTA, a visual storytelling project preserving the worldview of the U'wa indigenous community.
