Only when used right, technology will let everybody enjoy life and maybe even prevent the end of our universe. Let’s make this transition as smooth as possible — exploring small & big challenges, harmonizing physical & digital worlds while having lots of fun.

I am a German-Nicaraguan interaction designer based in Berlin. I joined Fuxblau, a Berlin service design agency, in the spring of 2014 as their first employee. Our mission: translating user needs into business models. This includes research, wireframing, prototyping, testing, visual design and running workshops. Currently I am finishing my Interface Design Bachelor at FH Potsdam and evaluating new opportunities.

preparing for retirement

preparing for retirement

As part of an internal project at Fuxblau, Birga, Maya and I set out to help young people prepare for their retirement during a 5-day design sprint. We are currently working on an in-depth blog post. For a more comprehensive picture of our work visit

“I'll start thinking about it when I am an adult.”

We were not surprised by our guerilla research. Young people either just ignored the topic all together or just didn't feel ready to start saving yet. After clustering our first impressions we created two paper prototypes. This prototype primarily helped us open a dialogue rather than just testing its features and usability. We talked to 4 people between 26 – 32 years old and discovered the following patterns:

1. Feeling overwhelmed and not knowing where to start.
2. Having the impression it's not worth it until you have a stable income.
3. Not feeling comfortable commiting to monthly payments as you never know where you'll be in 2 or 3 years from now.
4. A general distrust towards non-independent consultants.

Support the user through all phases

By creating the customer journey, business model canvas and stakeholder map we identified gaps and opportunities in our concept. The service ideally supports the user through all the phases; getting interested, recognizing the importance of starting now, understanding the current financial situation, identifiying saving potentials to actually start saving and staying motivated. This lead us to create several mini prototypes, each adressing one of these phases. Maya and I worked on the missing screens and put together a clickdummy.

Sparking curiosity

A website with video-interviews of real people talking about how they prepare(d) for retirement. You are able to filter by job industry or status like employed, unemployed, studying or retired.

Conveying urgency

The quick pension calculator compares your expected pension with the ideal pension to make it more tangible. In this case the ideal pension allows you to rent a 2 room apartment, go out for dinner once a week, go on two holiday trips a year etc.

Understanding financial situation

After entering your income and expenses it will calculate how much you could theoratically put aside each month and point out saving potentials like buying less coffee, cooking more at home or canceling that subscription you barely use.

Taking action

Depending on how much you are willing to save it will suggest you 3 investment options shortly explaining their pros and cons. Those who want professional and personal advice can directly book an appointment with one of the independent consultants.


On friday we tested our concept with one of the people we interviewed at the beginning + one who never heard of our concept before. We were positively surprised how well all those mini-prototypes worked together. Some improvement suggestions:
1. Shorter videos, max. 2 minutes.
2. Better filters to find a person with a similar background or situation.
3. Being able to adapt the ideal pension to my lifestyle.
4. Being able to precisely track my finances.

This fictional documentary is the result of a course on speculative design supervised by Boris Müller. Together with my friend, flatmate and fellow student José we developed the concept and scenic design. Frida helped us with the costumes and Jan with the camera and technical advice. Instead of a script, each of the actors recevied a detailed character description. I then played the role of the interviewer which allowed them to improvise and be more authentic on set. In–depth making–of is in the works.

tangible time indicator

Superclock is an internet-connected clock that shows you when your next train, bus or tram is coming. The ceramic spheres are linked to a specific public transportation line: once a sphere is positioned on the clock face, it will move, signalling the next departure.

Inside each ceramic sphere is an NFC chip and a tiny magnet in order to recognize and move it around the clockface.

MVP & development at uni

In 2013 my friends Giuseppe and Emanuele built a little bus that would change its color between red and green according to the waiting time. I got inspired and kept working on this concept during my first university course at FHP supervised by Reto Wettach. My final prototype had two discs showing the waiting time for the subway U8 going in both directions. By rotating the disc you can postpone the departure time.
With this prototype we participated in the Betapitch and won 6 moths of coworking space. Emanuele then moved to Berlin and we continued working on it.

Exploring interactions

Just adding another screen to our daily life is not the most elegant solution. In the coming months we developed a few more prototypes with rather complex gear mechanisms. The first were designed to work in public spaces and thus had no direct interaction. Eventually we decided to design it for the private space as the uses cases are more interesting. Now it had a more direct and tangible interaction that worked for the majority of uses cases at home. After the initial setup you place one the of the spheres on the clock face and it shows you the next departure of one public transportation. Simple as that.

Our last prototype

After struggling for months with the technical execution we decided to make a final high-fidelity prototype before putting the project to rest. We just didn't see enough demand for this kind of product and didn't feel comfortable investing more time without the required technical expertise to launch an IoT product. In the coming weeks I turned the wooden body using a wood lathe, made the ceramic spheres and front plate with the help of a local ceramics workshop and laser cut the clock hands. Just add some velcro, magnets, cable, servo … tada!

Urban Dataobjects
data physicalization in the city

We wanted to confront and disrupt people from their daily routine. Thus we brought the data back to where it came from: the public space. For each data set we selected its appropriate medium and context.


It's such a pity that so many interesting data-driven stories don't reach the general public. So why not take the data and put it where people can't look away? When I read the description of Boris Müller's course I had to join: translating abstract data into tangible structures. After presenting my idea we ended up being a group of 5: Mario, Merle, Philipp, Thomas and me. Thomas is deaf and therefore always had a translator during the course. This meant we couldn't discuss ideas for hours and as fast as we usually did. It made us communicate more efficiently by keeping our conversations short and sweet while always sketching out our ideas.

First explorations

My fellow team mates were a bit sceptical at the beginning. But after an aftertoon stroll through Berlin and a prototyping session it quickly became clear that there were endless possibilities. After creating small data objects in the city it became clear they had a stronger impact if its topic was combined it with the appropiate location and medium. During the next phase we combed through the data of the Bertelsmann Foundation looking for interesting topics, collected promising locations and made first material tests.


As we had different interests, each of us developed and lead their own data object. We exchanged our ideas, refined them and adressed any issues together. Once the concept, location and material was ready we went out in groups of at least three: one person would help out building the data object while the other one documented the process. At the end Philipp put our all material into this lovely video.

Create a cube 36 × 36 cm

The Berliner Box emerged during a course supervised by Hermann Weizenegger. The challenge: create a cube 36 × 36 cm. That semester I had just moved to a new shared flat and was annoyed by having to disassemble & reassemble my furniture, putting my things into cardboards boxes etc. So I set out to create an affordable and easy-to-handle cube for the typical student in Berlin moving at least once a year. The first weeks we visited metal, wood and acrylic workshops around Berlin and started creating our first concepts out of cardboard.

DIY approach

After coming up with the basic modular concept the bigger challenge was to combine the right material with the right manufacturing process. During the course I imagined it to be a DIY process to keep the box as affordable as possible. You would buy the pre-cut wooden panels at your local carpenter and put them together with wooden dowels, hammer and express wood glue. Unfortunately only a few people seemed eager to go through this tedious process just to avoid the assembly costs.

Manufacturing process & price

During the next 2 years  I sold more than 50 Berliner Boxes. I currently have various prototypes in my flat with different materials, thicknesses; some even have holes on the side to make them easier to carry.
Price-performance ratio dilemma: People love the look and price of the OSB material. Multiplex however, is way more durable and environmentally friendly but also more expensive. And people who could afford the multiplex version usually don't move that often.

Want some Berliner Boxes?
Get in touch:

Currently I produce the Berliner Box on demand. I could imagine creating a proper DIY video tutorial, crowdfunding a batch of DIY kits in Berlin, finishing the CNC design and uploading it to Opendesk or cooperating with a bigger company. But I guess I will not reopen the case until I move again.
