Hi, I’m Jack — a Senior UI/UX Designer based in the Bay Area with 10+ years of experience creating clean, scalable, and user-centered digital experiences across web and mobile.
I specialize in design systems, responsive UI, and visual identity, blending UX structure with visual clarity to build products that feel intuitive and thoughtfully crafted. I enjoy transforming complex ideas into simple layouts, smooth flows, and polished visuals that support real user needs and business goals.
My background spans startups and in-house teams across the US and Asia, including Psync/iHealth, VAVA, and Hack Chinese. I work closely with developers, product teams, and marketers to ship data-informed designs and consistent multi-platform experiences.
If you’re working on something design-related — product, UI/UX, or visual systems — feel free to connect.
