Remote UX/UI work – Sofi Mateo designing digital products while traveling the world."

UX/UI Designer obsessed with human behaviour

Hi, I'm Sofi — Product Designer turning user friction into flow

I design onboarding flows, paywalls and behavioral nudges that help digital products grow.

Onboarding redesign focused on increasing free to trial conversion, reducing drop-off, and enhancing perceived value. By incorporating personalisation, social proof, and interaction variety, the new flow aims to drive higher activation and subscription rates.

I redesigned the site to reduce cognitive overload, simplify booking paths, and make it mobile-friendly — resulting in +727% mobile engagement and +361% desktop interaction. 

As a UX Consultant, I helped FIHF clarify its mission, structure its content around user needs, and build trust through clearer storytelling. By combining interviews, analytics, and heuristic audits, we turned a confusing site into a focused platform that guides scientists, farmers, and donors toward action.
