About Me

Designing with Purpose,
Passion & Precision

Hi, I'm Sophia — a senior UX/UI designer based in San Francisco with over eight years of experience helping startups and Fortune 500 companies design products people genuinely love to use.

My approach blends rigorous user research with a strong sense of visual craft. I believe the best design is invisible — it simply works, and it delights. Whether I'm shaping a zero-to-one product or scaling an established design system, I bring the same care and curiosity to every pixel.
