Powering our software with

powerful Design Systems.

Powering Software through Design Systems   ›  starting 2014



I develop & maintain the User Interface Framework (UIF) and our Style Guide "Base" and implement together with AppDirect's Engineers and Product Designers our visual vision.

I also launched various products for the AppDirect ecosystem, starting as a prototyper till the final front-end implementation.


Re-inventing Recommendations   ›  2012-2014    ›  Acquired by Walmart Labs


The responsive Catalog is the starting point to find products you may luv.

Luvocracy is a social shopping site described by Mashable as "Pinterest for people who actually want to buy stuff."

I helped grow the site from hundreds to hundreds of thousand of users by rapidly implementing front-end solutions including a responsive web framework and time-saving reusable components.

Building a catalog service with all kinds of cards drastically simplified the development. The concept was so successful that we decided to implement it across all platforms and devices.

Luvocracy got acquired by Walmart in July 2014.


All around Typography

A mix of UI elements I contributed to Fontshop's store.

I started at Fontshop International in July 2011 as a front-end developer at the office in Berlin, Germany and later in 2012 in San Francisco.

It was fascinating to work with a global team around all aspects of professional typography, web development and app development.   ›  2009-2012

My favorite project was the "Random Fonts" page, a high-performance font discovery tool.

I independently designed and developed the feature. It works on all kinds of mobile devices as well.

The special work situation created amazing opportunities to collaborate together with typographers and developers from both company offices.


Empowering collaborative editing around the world

I worked as a summer intern at Wikia in 2010. The timing was ideal because a complete front and back-end redesign happened during my internship.

We used the latest front-end technology to convert elements into HTML 5 and CSS 3 with the help of SASS. Wikia‘s redesign was a great success story.

My implemented feature, the "Latest Photos", turned into one of the most popular features on the website.

One of my user experiments was the "User Interview for your Profile Page". Users were asked questions to populate their User Profile Pages.   ›  2010
"Oasis" - Wikia's new skin I worked on in 2010. Today it's still the foundation of a highly scalable wiki-platform that became one of the top US-websites.

Building an online place for community groups

Big Tent‘s web application provides a platform for community groups to organize and connect online.

My main focus was implementing and developing the user interface and user experience design.

The free platform is easy to use, but also provides powerful group management features and is completely customizable.

The site‘s revenue model is based on nonaggressive advertisement.

Buzz Pages

What I like about the Group Buzz page is that you can see all group activites compressed in one place. The simplistic layout makes it very easy to navigate through the content.

Public Profile Page

The Public Page was one of my favorite projects at Big Tent.

I like the idea of changing the large polaroid image based on the promoted "group of the week. " The admins can replace it with their own group image – it shows in a wonderful photographic way the variety of Big Tent‘s group life.   ›  2007-2008
Buzz Pages present all group activities in one single view. Like a news feed.
I implemented BigTent's public page. The photo dynamically changed time to time.
