Previously I worked in the hospitality industry and as a freelance illustrator, which made me realise that I love solving problems and help others have a pleasant experience; this translates well into user experience design, and having an excellent eye for details from previous art studies in Spain, translates well into user interface design.

My natural curiosity and interest in continuous learning have driven me in the pursuit of a UX/UI career: building engaging experiences is what drives me. I'm currently digging deeper into designing interactions that make technology feel effortless.
