As a specialist in UI/UX design and Product Design, I offer expertise ranging from user research (discovery, user tests) to the design of mobile-first, responsive, and user-centric interfaces.

-Process & Delivery:design-product-tech workflows, cycle reduction, incremental and iterative delivery.

I combine operational and strategic expertise, capable of intervening in all aspects of product design, from brief to delivery. My practice is user-centered, yet very pragmatic and business-impact oriented.
