Product Designer with 5 years of experience, I support teams from the scoping phase to the definition of concrete digital solutions, combining user needs, business objectives, and data analysis.

My work is based on a comprehensive UX approach: user research, qualitative and quantitative analysis, problem structuring, recommendation formalization, and definition of journeys and features.
I also work on UI aspects when the project requires it, through the production of wireframes, prototypes, and design deliverables that align teams and drive decisions.
I work in B2B and B2C environments, collaborating with business, marketing, product, and IT teams, including on topics related to AI and the integration of conversational tools into the user experience.
