What I'm looking for

I seek remote roles where I can lead end-to-end product design, build scalable design systems, collaborate cross-functionally, and deliver measurable product and 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 design systems that drive measurable improvements in customer engagement and business performance.

I partner closely with cross-functional teams to translate insights into intuitive, pixel-perfect experiences, having led initiatives that produced 214k account links in 90 days, increased cross-brand redemptions by 37%, and improved new member enrolments by 5.6%. I bring strong product thinking, systems thinking, and a proven track record delivering production-ready assets and design QA standards.
