What I'm looking for

I'm seeking a Senior/Lead Product Designer role at a B2B SaaS company where I can lead UX strategy, build scalable WCAG-compliant design systems, partner with product and engineering, and solve complex data-driven UX problems.

I'm a Senior Product Designer with 8+ years of experience focused on B2B SaaS and enterprise UX, specializing in designing data-heavy platforms, building scalable design systems, and defining UX strategy.

At Ninety Percent of Everything I led UX strategy for maritime performance tools, boosting product adoption by 400% and engagement by 200% within one year while developing and maintaining a WCAG-compliant design system used across squads.

Previously at Workable I redesigned ATS and candidate database workflows, delivering 3x faster resume uploads and 30–40% faster workflows; as a lead I managed small teams and built global design systems that improved visual consistency and delivery speed across platforms.

I run user research, usability testing and A/B experiments, partner closely with product and engineering, and use tools like Figma, FigJam, Miro and ZeroHeight to deliver accessible, data-driven interfaces; I also mentor designers and speak on product thinking for complex apps.
