• Built personas and journey maps with a teammate, plus a weighted decision matrix against 4 competitors, to prioritize a phase-based status timeline and public/private scoring. Iterated the leaderboard through 3 rounds based on real feedback from live camp participants.

• Led the design of the user-side experience end-to-end across 11 screens on a 4-person team, from personas and journey mapping to hi-fi prototypes.
