" Every THING is an interface! "

I believe every object – whether created by humans or occurring naturally – is an interface. Used consciously or unconsciously, every object has its own language for communicating its purpose to its “user”. The clearer that language is, the more easily and successfully the object can be used for its intended purpose.

I’m Karl, a UX Technologist and Senior Developer from Germany with more than 12 years of experience creating complex digital products.

As a hybrid of developer and designer, I’m constantly exploring new techniques to expand my skill set. With a background in software development and user experience design, I bridge the gap between functionality and aesthetics.

My Creative Process

Clarify the purpose, audience, and outcome before shaping the solution.

Showroom

Here you'll find a mix of visual experiments and creative ideas I've brought to life in my free time over the past few years.

Disclaimer: NDA's prevent me from publicly showcasing customer projects or parts of them - the showroom is not a professional portfolio.

ThreeJS Globe

Using a specular map of the Earth, a point matrix is generated and visualized with Three.js/Fiber.

Three.js, React

Water Levels

Knowing the water level of the rivers in my area is crucial for a fisherman like myself.

Satellites

3D visualization of all publicly documented satellites that orbit Earth at this moment. Data provided by NORAD.

Unity/WebGL

Orbit Sandbox

A colorful simulation to explore mass, momentum, and gravity. Swipe or drag to create objects and watch them interact with the central star.

Unity/WebGL

Cube Puzzle

Recreating the famous cube puzzle hardly anyone can solve. I wanted it to have a realistic look and feel and straightforward controls.
