About Lisian

I’m a senior product designer with over 12 years of experience designing and building digital products across SaaS, AI, fintech, healthcare, and consumer platforms. Throughout my career, I’ve worked closely with founders, CEOs, and engineering teams to turn complex problems into clear, scalable experiences, often owning both product strategy and execution.

In recent years, my work has been deeply focused on AI-driven products, including generative AI, conversational interfaces, and data-informed UX, helping teams design systems that feel human, trustworthy, and impactful. I’m comfortable operating from zero-to-one as well as scaling mature products, bridging design, product thinking, and emerging AI capabilities to create solutions that deliver real business and user value.
