My name is Christian and I am specialized in design strategy, branding, user interactions and interfaces with more 14 years of experience.

Combining my human-centered design skills with a broad knowledge of visual, digital and physical tools, I am committed to create engaging and impactful user experiences, and I am especially astute at devising simple and effective design solutions from complex conditions. I’ve worked in a wide range of industries, including automotive, financial services and telecoms.

Lately I’ve focused on the intersection between design, strategy and org while establishing innovative environments and the design discipline as an overarching culturale working aspect.

Outside of work I am driven by a curiosity to discover the unfamiliar, and is constantly in pursuit of the new. I am really into music, art & design, typography and scandinavia. Otherwise I can be found engaging in one of my various outdoor activities, like snowboarding, surfing, or swimming.

What we as designers need to be aware of, is how much more can we contribute to that particular request. So asking yourself “why” helps you create context for yourself, and also challenging the ideas and looking at them critically.
