    Working with Chun was a pleasure. He played a key role in shaping several of our most important internal tools and the client-facing app. His ability to translate abstract problems into elegant, user-focused designs made a real difference to our product delivery.

    Our product had a lot of moving parts, different user types, evolving requirements, and high expectations. Chun brought calm, clarity, and fast execution. His ability to translate messy ideas into intuitive experiences was exactly what we needed.

    Chun was a fantastic UX partner – quickly grasping complex data challenges and translating them into clear, interactive design concepts. He played a key role in developing a UX proof of concept that brought our product vision to life, and helped turn dense, technical content into user-friendly visuals to enhance both client engagement and thought leadership. A pleasure to work with.

    It’s been a pleasure collaborating with Chun for nearly four years. He transformed our design system, bridged Figma with Android APIs, and elevated both iOS and Android experiences. His work enabled a small team to maintain a 100-screen app efficiently. Beyond his skills, he’s collaborative, respectful, and positive. Any team would be lucky to have him.

Beyond Design

Away from the screen, I run, organise small communities, and make things by hand.

It keeps my thinking sharp, my empathy grounded —
and reminds me to slow down, especially when my little one is winning the negotiation.
