Hello, my name

I am a Brazilian seasoned product designer (UI/UX), based in Berlin. I’ve designed products for fintechs, real estate, e-commerce, sports and food industry.

And this is Marie Curie

About me

I embarked on my design journey back in 2011, working for an e-commerce company. Over the years, I've had the privilege of learning from talented individuals across diverse industries. In my current role as a Senior Product Designer at Ziegert, I take charge of the end-to-end design process, leading a team of two senior and one junior product designer while continuously advocating for data-driven and user centric design.

My principles:

Simple solutions to test great hypotheses.
Transparency and data boost team’s creativity.
Go beyond the boundary of "design"

Beyond work

Keep running with my wife, Ana

Bruce Lee once said that running is the most democratic sport, all you need is a par of shoes. I enjoy running as this is both a way to enter a meditative state and also a good exercise to do with Ana.

Supporting “Circo de Québra” project

Since 2016 I colaborate with "Circo de Québra" with my design and strategic expertise. Together we promote cultural and enviromental activities in alleys and stairways in São Paulo’s outskirt.

“Memoráveis” Research group

I research, write and learn in a group of 43 Brazilian researcher associated with multiple universities. Currently, we are working to publish a design research methodology book, and I am one of the authors.

Cooking delicious vegan food

I cultivated my passion for cooking under the influence of my grandfather and mother. Preparing vegan food presents a creative challenge for me, offering a delightful opportunity to serve delicious meals to family and friends.
