Making trading approachable for first-time investors

I joined as the first designer to help bring FiinTrade to life. I worked with the Product Manager and Business Analysts. We started by interviewing new investors to understand where they were getting stuck. Most of them said the same thing: too much information, not enough guidance.

With that key insight, we focused the product on helping users ease in gradually. I designed FiinTrade so that information would build/show step by step, rather than all at once. A widget-based dashboard let users control what they saw, keeping things relevant and manageable. Real-time, verified data helped users feel confident in the numbers, and light and dark modes made sure charts and heatmaps were always easy to read.

Over six months, I designed more than 800 screens. I collaborated with Japanese advisors, local developers, and early users to test and refine the UX. When parts of the layout and data presentation still felt too heavy, I simplified them again. The goal was clarity at every step.

As the product grew, I moved from solo designer to Senior, then Lead, building FiinGroup’s first design team and setting up design principles and review systems as we scaled.
