Overview

Big League AI needed to simplify a confusing journey that left athletes and parents unsure how to improve. I redesigned the experience around a clear sequence that connected motion capture, analysis, and training into one continuous development path. This helped athletes understand what to do next and why it mattered. The new system also set the groundwork for expanding into pitching, team features, and richer analytics.

The State of the Product

Big League AI is a baseball performance platform that converts raw swing video into personalized, metric driven training. I joined in mid July ahead of an October relaunch to rebuild the athlete journey from the inside out. My focus was to reshape the Measure to Assess to Train loop so the experience would guide athletes with clarity and purpose while giving the company a scalable foundation for athlete development. What started as a confusing sequence of disconnected screens became a coherent training system that athletes, parents, and coaches could trust.

Solution

Designing an intuitive sports-specific journey

Through a focused UX review and rapid iteration in Figma, I streamlined the Measure → Assess → Train → Re-measure journey into a simple, motivating loop.

  • UX clarity: Redesigned navigation, simplified onboarding, and decluttered layouts.

  • Visual cohesion: Introduced a modular design system with baseball-inspired icons and iOS-native patterns.

  • Contextual feedback: Translated advanced metrics (like exit velocity and launch angle) into visual dashboards and color-coded insights for instant understanding.

Outcome

A redefined digital training companion

The redesigned app delivers an experience that’s clear, fast, and built for athletes. With intuitive flows, modern visuals, and accessible metrics, players can now see their progress in real time — and developers have the tools to bring it to life efficiently.

“The new design feels built by baseball people — everything just makes sense now.”

Impact & Next Steps

The redesign set a new visual and usability standard for the client’s platform, enabling smoother onboarding and faster iteration. Future work includes real-time coaching feedback, expanded web dashboards, and integration of AI-based performance insights — bringing the same simplicity to more players and coaches worldwide.

Would you like me to make a version formatted for a web portfolio page (with headings like “Challenge / Solution / Outcome” in short blocks and image-caption prompts)?
