About
I’m ck71
“For 17 years I built for agencies. Since 2026 I’ve been self-employed.”
From those agency years, among others work for Mercedes-Benz, Werder Bremen and Publicis.
On my own account I’m building Nit, a light meter for film photographers, and calendar.ck71, a GDPR-compliant team calendar.
As a trained toolmaker, the joy of building stayed. Today it’s bikes and code instead of tools.
On the side I photograph — places almost forgotten, things that stay, moments without drama.
And I listen to a lot of vinyl, because some things just work better in analog.
