What I'm looking for

I’m looking for a product-focused role where I can architect scalable design systems, turn complex backend logic into intuitive UX, and partner with teams on business milestones to minimize friction and maximize engagement.

I’m a UI/UX/Product Designer with 6 years of expertise, evolving from graphic design into interface design and systems architecture. I design intuitive experiences for complex, high-stakes ecosystems across Proptech, Web3, EV, and AI platforms.

I’m expert at translating technical backend complexities into scalable design systems that drive engagement and minimize operational friction. I architect interface frameworks, end-to-end flows, and user journeys for decentralized infrastructure, token utility experiences, and streamlined transaction experiences.

I also align design strategy with major business milestones and brand partnerships, building unified visual architecture across products and ensuring consistency across decentralized components. From migrating platforms to a unified design system to creating responsive web/mobile experiences, I focus on user trust, operational clarity, and scalable product growth.
