About
I’m a product designer with roots in architecture and urban design, driven by a deep interest in how people interact with space, both physically and digitally. I approach design with a strong focus on structure, clarity, and human-centered thinking. My work spans systems that help users navigate complex information, through clear interfaces, thoughtful interactions, and spatial experiences like maps and AR/VR. I enjoy prototyping with code to bring ideas to life, and I’m focused on making technology more grounded and human. Experienced in UX design, product strategy, and usability testing across industries including e-commerce, technology, and retail.
