About me
I’m a Product Designer with 10+ years in B2B SaaS and a PhD in Interaction Design. I help teams ship clear, usable, and scalable software by combining strategic research, lean execution, and strong design systems. I relish complexity, and transform it into simple interfaces. Experienced in leading design efforts, mentoring, and collaborating with product and tech to shape roadmaps and elevate product quality. I’m self-starting, proactive, and I love to learn.
