Hello,Bonjour,Xin Chào

I'm a product designer.

My name is Alex Guyenne. I’m a Product Designer, iOS developer and Entrepreneur from France living in Berlin, Germany. I believe that design is quintessential, but should never jeopardize the quality of a product.

I have a passion for clean and simple interfaces.

One of the greatest strengths about being a designer with a computer science background is that I can handle the graphical aspects of a project, as well as fully understand, participate and even lead the technical aspects of those same projects.

I am resourceful and not afraid of taking risks. I speak English, French and Vietnamese fluently.

I am a co-founder of Tangoo, and currently a mobile UI/UX designer at DaWanda GmbH. Let's connect on LinkedIn.

What I do


With years of experience in international companies as well as start-ups, I have been involved in a number of different projects. I specialize in making clean interfaces.


I'm primarily concerned with how the product feels. A given design problem has no single right answer. I explore many different approaches to solving a specific user problem.

iOS development

Beyond its design, I can develop your product from a visual concept to a fully functional iOS app.
