A video, shot from above on a white table. A hand moves a smartphone over a magazine spread. The pages are white with subtle wireframes of text and images instead of a real design. The hand moves the phone above the spread and its display shows some kind of radar animation while scanning the pages. It also displays the content of the pages but with inverted colors, almost as if the screen was a piece of glas you could look through onto the table. The hand places the phone onto the magazine and drags it around slowly. The screen indicates some kind of locked state once a certain position and orientation is reached. The content below the phone, printed on the magazine page, turns into an interactive representation on the phone’s screen. The hand flics and taps it, scrolling the content or triggering a simple wireframe 3D animation.
A screen recording showing only one UI component in dark color mode and flat style. The component is a box with five horizontal slider controls and an input field on the right. The cursor moves around and drags the knobs of the sliders as the corresponding values inside the input fields update. The values are percentages and react to the sliders, always adding up to 100%. Each input has small a lock-button as well. The cursor presses some of these lock buttons and they become red, representing their active state. The locked values and sliders are now static and do not react anymore as the cursor manipulates the other unlocked sliders — the values however still add up to 100%.
I help people to build digital products, typically in a temporary leadership role at the intersection of design and development.
The result of my work ranges from full-scale Design Systems for enterprise-level software to small, bespoke web apps.
My goal is to create useful human-centered systems, and to share my knowledge along the way. My clients should always be able to carry on confidently after I leave.
I have been working with large corporations and small start-ups across various industries for 20+ years. These days, I am a freelance consultant operating under the company name Sudo.
From 2017 to 2019, I built and led the cross-functional team at Yoshino, an agency specializing in healthcare-related digital products.
Since 2013, I have been teaching a four-semester course on Interaction Design, with an emphasis on Human Centered Design, at S4G (School for Games).
From 2007 to 2009, I worked as an art director at Gosub, a now-defunct digital agency in Berlin that specialized in immersive and playful interactive brand experiences.
I help with strategy and the scaling, auditing, or improving of existing UX/UI designs.
I manage and grow teams, align stakeholders with designers, and provide design direction.
I deliver end-to-end design work across multiple disciplines: branding & logo design, strategy, webdesign, UI/UX, and more.
I translate designs into code, caring deeply about visual precision, flawless interaction, and smooth performance.
I create strategic assets, document artefacts, build processes, align crossfunctional teams, and drive adoption.
I design and facilitate tailored, engaging workshops, and work with teams or individuals to support their growth.
When I was a child, I couldn’t resist taking things apart and marveling at their inner workings. That urge never left me.
I remember when I first saw a
Three years later, in 1994,
Now that I could draw in the digital realm, I wanted to figure out how to make things to respond and interact as well. Luckily, right at this point, the internet became a thing. I learned HTML to build my first website at the dawn of the browser wars, around 1998, still mangling <TABLE>s and spacer GIFs. Back then, the web was like a window from my teenage room into the world. Everything felt possible and it was an exciting phase of discovery. I learned so much by trial and error and hitting ⌘+Z.
In hindsight, my curiosity, my admiration for great craftsmanship, and my ability to learn autonomously shaped my attitude towards my professional work. I am still driven to understand how things work, especially in larger contexts. I aim to build things that are robust, functional, and delightful. And I genuinely love to inspire and teach others along the way.
Apart from tinkering, I have always been into music, especially the
