Product | UX/UI Designer

Hey there! 👋🏻

I`m Product designer with 3 years across SaaS, e-commerce, and healthtech, focused on conversion and retention through data-informed UX. Simultaneously led design on two live products (B2B SaaS platform + e-commerce), improving conversion rate by 12% and cutting feature drop-off to ~10% through flow optimization and design-system work. Skilled in UX research, hypothesis validation, prototyping, and design systems. Comfortable owning a feature end-to-end — from hypothesis to release — and collaborating with international, English-speaking teams.
