About / Tayana Souza
I design the systems behind experiences that feel simple.
I'm Tayana, a Senior Product Designer based in Porto with more than 12 years of experience creating digital products across automotive, fintech, telecommunications and B2B SaaS.
I work where user needs, business goals and technical constraints meet. My contribution goes beyond screens: I bring structure to ambiguity, align multidisciplinary teams and build systems that help products scale with confidence.
What I bring
From ambiguity to a product people can trust.
I work across strategy, experience architecture and interface design. I stay close enough to the details to protect the experience while keeping the wider team aligned.
Strategic product thinking
I turn research, business requirements and technical constraints into a shared product direction teams can act on.
