Coaches and players have endless performance video and very little usable insight. Knowhere set out to turn raw pitching and batting footage into clear, decision-ready guidance for player development.

It had to serve two very different audiences: professional and enterprise teams on one side, individual athletes on the other. The hard part was making dense biomechanical and performance data readable and decision-ready without dumbing it down for experts.

I led UX end to end: user research, competitive analysis, dashboard and information architecture, and the modular UI system that scaled the product from B2B to B2C.

I shipped the actual web and mobile apps that coaches, analysts, and players use.

I tested content cards against data tables to find which was clearer and more usable for displaying sports analytics. Running that comparison head to head meant the layout was validated, not guessed. I then enforced a clear information hierarchy so the decision a coach or player needs to make comes before raw data density.

The signature decision was structural. Rather than build two products for two audiences, I built one modular UI library with standardized patterns. That single system is what let the same product serve a professional front office and an individual player on their phone.

It was also constrained work. Engineering was limited to the Material UI component kit, so I adapted design ideas to fit what the team could actually build, while keeping clarity and usability intact.

The modular library made the product portable across audiences. The same patterns dressed up for an enterprise analyst and down for a recreational player, which is how a B2B tool became a B2C one without a second build.

Knowhere is used by MLB teams and became the number one sports app in Taiwan. The company raised ¥480M, led by Globis Capital Partners, during my time on the project.

The project reinforced designing with a growth mindset: building solutions that stay adaptable for long-term use, and keeping teams and stakeholders aligned through delivery. One system scaled further than two products ever could have.
