Hi, I'm Hyeonjee.
My friends call me Jee!
I'm a Product Designer based in the U.S., with experience in creator technology and consumer health. My work spans web and mobile product design, from early exploration through launch and iteration. My background in visual design shapes how I approach information hierarchy, typography, and visual consistency.
At Passes, I led the redesign of a livestream experience across native mobile and responsive web. While designing new monetization and moderation features, I identified limitations in the existing interactions that isolated feature additions could not address. I proposed a focused redesign of the livestream interface and creator-facing tools, defining role-based workflows, permissions, and interaction behavior for creators, moderators, and viewers.
Previously, at LifeX (formerly Humanscape), I designed experiences for Bomee (formerly Momitalk Global), a pregnancy app. I led the design of its AI-powered assistant from the initial MVP through launch and subsequent redesign, introducing clearer conversation topics and entry points. Following the redesign, conversion to sending at least two messages among chat visitors increased by 72%.
I also redesigned health tracking to connect user logs with meaningful feedback and insights. Next-week repeat logging among users who completed a log was 2.0–2.7× the previous feature's baseline across three markets. For family sharing, I simplified invitation and access-management flows, reducing friction in the process. Accepted invitations more than doubled within the first month after launch.
I work closely with product managers and engineers to define interaction behavior, resolve edge cases, and refine designs for implementation. I've also used post-launch behavioral data to evaluate engagement and identify opportunities for improvement.
