About

I'm a UI/UX designer based in Hong Kong with around 3 years of experience designing mobile and web products. I care about clean visual hierarchy, intuitive flows, and crafting interfaces that feel effortless to use. I work day-to-day across the full design process, from user research and wireframing to high-fidelity UI and design systems. I'm comfortable owning a feature end-to-end, partnering closely with engineers through to release, and iterating based on real user feedback. On top of product design, I have hands-on experience building and maintaining design systems in Figma, which helps teams ship faster while keeping the product visually consistent. What I bring: - Strong UI/UX fundamentals across information architecture, interaction design, and visual design Practical experience with user flows, wireframes, prototypes, and usability testing - Comfort owning a feature from discovery to design hand-off and release support - Working knowledge of design systems and component libraries in Figma for scalable product design - A pragmatic eye for accessibility, responsive design, and design-to-development hand-off - Always open to connecting with other designers, founders, and teams building thoughtful products.
