Technical Product Owner at Nexon who improved SIREN metric creation success from under 20% to 60% and automated SDK documentation at Sendbird.
What I'm looking for
At NEXON Korea, I owned four data products for operations and business teams across 40+ games. For SIREN, I used behavior logs and onboarding observations to prioritize a beginner-focused redesign, raising metric creation success from under 20% to 60%.
At Sendbird, I built an agent workflow to draft and review SDK documentation, reducing average update lead time from 10 business days to 3. I’ve also shipped independent products and worked as a freelance Product Manager on a wearable sports data platform, shaping its phased MVP and delivering user flows and wireframes.
Experience

Reduced documentation update lead time from 10 business days to 3, with 50% of AI drafts approved without edits.
