About Benjamin

Do you have data, a complex subject, or a territory to tell? I design visual supports, maps, and data visualizations that make information readable, clear, and enjoyable to navigate.

As a designer for ten years (public services, cultural institutions, brands), I now focus on cartography and data visualization. What sets me apart here: a true designer's eye, still rare among technical profiles. Your data deserves better than a default graph; I give them a refined form, designed for your message and your audience.

What I can help you with:

- Visual design and identity
- Infographics
- Data visualization
- Cartography and GIS
- Editorial and print

Two things I bring to every project: the rigor and attention to detail required by dense data, and visual communication that makes your message stand out and be understood.

Topics close to my heart: climate, urban planning, conservation, energy. But I take pleasure in shaping data from all backgrounds.
