TL;DR

I helped create the audiobook experience for O’Reilly’s mobile app, moving from a video-player workaround to a purpose-built, mobile-first audio solution. As one of two product designers, I led user flow mapping, competitive analysis, iterative design, and usability testing. Through unmoderated Maze testing, we used a diverge-converge approach to explore layouts and validated decisions, like chapter skip, playback speed, and mini-player behavior. With tight constraints (8-week timeline), we scoped an MVP while designing toward a full-featured vision. The result was a 150% increase of audiobook consumption on the platform and doubled app usage between iOS and Android devices within the first two quarters post ship. It continues to serve users well with minimal post-launch revisions.
