For three decades I’ve been shaping digital products across fintech, adtech, and startups—working in New York, Berlin, and Barcelona, and collaborating with teams of every size. My path has taken me from early intranet systems to today’s user-centered platforms, always with a focus on making complex challenges simple and intuitive.

Education: Argentina & New York

I studied Graphic Design at Escuela Superior de Diseño Gráfico in Rosario, Argentina and then continued my education at  Parsons School of Design and School of Visual Arts in New York City in the fields of design and typography with Ed BenguiatMilton Glaser and Martin Solomon as main instructors.

Sr. Web Designer, Art Director in New York

I started with web design in 1995 in Rowayton, CT, USA. Three years later, after a short period in Argentina, I moved to New York City to work at StarMedia Network as a Sr. Web Designer and then as Art Director. Early in 2000, Parsons School of Design appointed me to teach Diseño Web en Español for the Continuing Education department.

Creative Director in Barcelona

In 2001 I relocated to Barcelona, Spain, where I continued working as Creative Director. Four years later, I opened my own studio, working with leading companies in the fashion and payment businesses. In 2010 I moved to Vilnius, Lithuania for half a year.

Senior UX/UI freelance, Berlin & Barcelona, 2011–present

Since moving to Berlin I've worked as a senior UX/UI designer for clients across Europe and the US — sometimes embedded part-time in a product team, sometimes brought in as the sole designer on a project from start to finish. The work has spanned adtech, fintech, e-commerce, and enterprise software. At Adspert, a Berlin-based adtech SaaS company, I designed data visualisation systems, campaign management interfaces, and alert flows for a complex, data-heavy platform. At Verde Money, a US fintech startup, I was responsible for the entire public-facing website and dashboard UX. Other notable projects include a multicontinental intranet redesign for Tignum and a Material Design-based internal tool for Juwelo. Based in Barcelona since 2023, I work remotely with clients across Europe and the US — currently available for part-time embedded roles and 3–6 month contracts.

When I'm not working, I’m traveling as slowly as I can.

Teaching and Building Inclusive Tech Education at ReDI School of Digital Integration

Since 2016 I've volunteered as an HTML & CSS instructor at ReDI School of Digital Integration in Berlin, a non-profit that provides free tech education to migrants, refugees, and underserved communities across Germany and beyond. Over 20 semesters I've taught and mentored 400+ students, co-shaped the foundational curriculum, and helped onboard new volunteer teachers. It's some of the most meaningful work I do — and a constant reminder of why good design and accessible education matter.
