I’m a UI/UX Designer with a PhD in architectural history and 3+ years of experience shipping mobile products across games, health, and fintech. I blend systems-thinking from academia with practical UX craft—turning complex mechanics into clear, intuitive user journeys through research, wireframing, and interaction design. I lead end-to-end design work from discovery to usability testing and scalable design systems, and I collaborate closely with developers to deliver production-ready specs. Recently, I’ve shipped iOS apps to the App Store, redesigned authentication and onboarding for a trading platform, and used AI-assisted workflows to speed up design-to-development handoffs.
