One of the biggest design challenges was reconciling my clean, minimalist design style with Japanese user expectations. Japanese interfaces often present a large amount of information and multiple options on a single screen. As a result, clients would sometimes perceive competing products as more robust simply because they displayed more features visually even if functionally, they were not.

​

To address this, I made key actions and available features more visible and prominent without overwhelming the user. This included:

Making important options more discoverable without cluttering the interface.

​

Using color coding and bold typography to highlight critical metrics.

​

Designing a system of graphs that included one large, detailed chart per screen, alongside small previews of other relevant data giving users a quick overview while maintaining performance and clarity.

We also faced performance challenges, as some user queries were complex and time consuming. The design needed to balance a high volume of data with responsive performance and an intuitive UI.
