I specialize in transforming user research, business needs, and data insights into intuitive digital experiences. My work includes user journeys, heuristic evaluations, information architecture, interface design, wireframes, prototypes, and usability improvements for web and mobile products.

Throughout my career, I have contributed to projects for organizations and clients including Santander, Serasa Experian, Ben Visa Vale, Amil, AMBEV, Whirlpool, Boa Vista Serviços, and several fintech companies.

I have strong experience facilitating and applying Design Thinking, Design Sprint, Product Discovery, UX Research, usability testing, A/B testing, and agile practices. I also support design culture, collaborate closely with development teams, and lead design handoffs and refinement sessions.

I have played an active role in creating and evolving Design Systems, establishing visual standards, and designing consistent interfaces across mobile, desktop, web, and tablet platforms. My prototyping workflow includes Figma, Marvel, and Adobe XD.

In addition to corporate roles, I have worked as a freelance designer on e-commerce structuring, dashboard redesigns, email campaigns, and lower-complexity UX and visual design projects. I am focused on delivering practical, user-centered solutions that create measurable business value.
