Make digital experiences echo in Human minds

*with proper Human Interface Design

Mary, do you remember me?

No I don’t. My name’s not Mary, it’s Lea. I’m a designer from Munich.

I make products that have an impact in the medical field, technology, and science. My favorite challenge is finding the right balance between pragmatism and innovation. I designed for companies like Carl Zeiss, Google, Interhyp and Cognostics, collaborated with agencies like UX&I and Ettrics, and also worked on moonshots and digital grounds related to arts and culture. Despite loving and being proud of my work, I dread the idea of fancy portfolios.

So, your second name is Mary?

Oh no. But you’re almost right, it’s the German name Marie. I lost this part of my name sometime in the nineties. I would have kept Mary, though. It was Shakespeare’s mother’s first name.

Now you have to choose one of the following:


Counting Social

An app project that made me think about how social networks work. I learned a lot about the psychology of digitalised social interactions. Gamification was a cornerstone of the concept, so I started reading on the matter and soon discovered the works of Yu-kai Chou on Gamification and Behavioral Design. I was excited to apply this knowledge to create an app that users would become obsessed with.

I’m getting confused

Very good. Confusion can help make things more interesting and attention-drawing. It plays out nicely for creative purposes, and when you can assume that users come to a place to explore and discover information for the first time. Like a random designers portfolio. …

In other situations though, and especially when users are trying to get some very important task done, a confusing user experience can be neck-breaking for a could-have-been-successful product idea. My goal is to create frictionless and enjoyable experiences. A goal that starts with understanding who will use the product, under which circumstances and with what intentions.

Mary likes Design Systems

So do I! I don’t know Mary, but I’m starting to like her as well.

I have worked with different sized Design Systems and learned that, no matter the size, it’s crucial to maintain focus. Design Systems are indispensable if you want to achieve a high level of consistency and product quality. But when they reach a specific size, they can develop some scary momentum and start growing like a savaged garden. Then system designers face a real challenge – they have to decide when to start pruning branches and do some weeding without hindering the natural development. A design system has to evolve and adapt to ever-changing requirements and feature scopes. It can be challenging to keep things consistent while supporting each new user journey with the best possible design solutions.

Here’s a Mary. Are you happy now?

If not, let’s talk somewhere else. I’m running out of ideas here. These are your final options:


I play…

Minecraft, the piano, tennis, with polymer clay and Lego. One of those is a lie. Can you guess which?


I am a four (4w3)

Referring to the Enneagram, a system of personality typing that describes patterns in how people see the world. 

(╬ Ò﹏Ó)

I do not like…

Superficial, dishonest, close-minded, unempathetic, arrogant, chronically late people. And various sounds.

I have a life

A husband and two kids, no pets, and a strong need for quiet time. So better leave me alone. For real.
