About me

Helping people cross of things of their bucket lists, reimagining the travel customer journey with mobile devices and getting people togehter who are like minded while practicing lean ux and coding apps is my current job at Jochen Schweizer and Spontacts.

By evangelising lean ux methods and being the first to do usability tests at Jochen Schweizer, management understood how much value lies in ux work. Now there is a ux team with 6 people and an open position :-)

Before fully shifting to ux design I coded mobile apps, web apps and restful backend systems at CHIP.

While I was studying computer science in Berlin I was self employed. In that time I had the chance to work with some great photographers, retouching their editorials or beauty shots and developing their web portfolios.

Adding that up to my 3 year apprenticeship as a Digital Media Designer I have spend more then 10.000 hours in photoshop and illustrator pushing pixels and bending vectors :-)

Working and exploring this multitude of disciplines qualifies me as t-shaped person and allowes me to prototype even complex things without blocking other resources.

When I’m not working I enjoy my two kids, playing chess, taking some photos or chatting with my friends in 🇩🇪 german, 🇺🇲 english or 🇮🇱 hebrew.

How I work

My artifacts come in many different forms and fidelities. I draw a lot, and write a lot. I prototype with paper and Sharpies, Sketch, Figma, Proto.io, Form, AfterEffects and XCode. I visit our users, listen, investigate, learn, and ideate. I rigorously share and promote ideas and constantly incorporate feedback and critique.

Sometimes I´m out in front, exploring brand-new problem spaces, figuring out what to build. And sometimes I´m deep in the details of micro-interactions, figuring out how to build it. I lead two cross functional teams in design exercises ranging from day-long design studios to week-long design sprints.

I know form informs function and usability—that the surface layer doesn’t exist in a vacuum—and that means the partnership with the Product Owner, Visual Designer and Software Engineers is a two-way conversation


Working in an agile development process I rely on lean ux and design thinking methodologies. Iterative software development and UX are second nature to me and allow for rapid feedback loops and encourage collaboration within the teams. Dual track development discribes the loops I’m going through pretty well. People tell me I´m an anti-hero-designer which means I communicate clearly that all we have are assumptions and hypotheses, which I can transform to experiments so we can learn as much as possible about them as a team.

I like to start the design work with a clear hypotheses and outcome goal in mind which usually is the outcome of the „Learn“ step. The following methods help me to express and refine ideas so they can be implemented:


When your mindset is all about experiments, then you also need to think of how you want to evaluate them. The designs im building are based on hypotheses which are connected to clear criterias for success or failure. I´m using the following methods to evaluate my designs:


Before Building or doing anything its important to understand as much as possible about the challenge at hand. Results from Measure Step before can help to formulate new hypotheses. Sometimes when you want to launch a new product or epic you need to start from scratch. In this case I tend to collaborate with the team members and experts in the company even more to gain more insights. I´m comfortable with the follow methods:
