What I do
I merge UX and accessibility standards with research and empathy to create truly inclusive digital spaces.
I’m Andreia, and I help teams design inclusive, accessible, and user-centered digital products across sectors such as finance, public services, healthcare, energy, telecom, media and e-commerce.
I work at the intersection of usability, business goals, and human impact, driven by the belief that accessibility is not an add-on, but a core part of digital strategy.
