User-centered design

Leonardo Leite

Product Designer

UI Interaction UX & Visual Design


Design skills & approach

I am interested in all forms of human interactions with digital information and I mostly work designing, testing and helping the development of new products and new functionalities.

I keep my skill set balanced working in many areas, and I am always adapting to the latest tools and technologies. I have worked with Interaction Design, UI, Visual Design, UX and front end development.

My approach to user experience is user centre design based in data evidence to find and solve the problems and needs of our users combined with business goals and strategy.

I love to create Apps, POCs, MVTs, Prototypes, Wireframes, and see them tested with users remotely or in person.
