Designer with an eye for systems

Otávio Bonato

Lead UX/UI Designer

I am a Lead UX/UI Designer based in Budapest, currently working at EY. My focus is enterprise product design, where complex systems need to feel simple to the people using them every day.

My background spans consumer apps and large scale platforms, which gives me a practical view of both ends of product design, from fast iteration to long term system thinking.
