What I'm looking for

I seek remote roles where I can lead end-to-end product design, establish design systems, collaborate cross-functionally, and deliver measurable business impact.

I am a Senior UI/UX Designer with 13+ years designing scalable B2B SaaS products and complex data visualization systems for fintech, customer programs, and analytics platforms. I specialize in end-to-end product design, user research, and building maintainable design systems that drive measurable improvements in customer engagement and business performance.

I partner closely with cross-functional product and engineering teams to translate insights into intuitive, pixel-perfect experiences, run usability and A/B testing, and establish design QA standards. My work has delivered clear business impact, including rapid account-link growth and increased cross-brand redemptions, while maintaining strong attention to detail and a systems-thinking approach.
