About Yejin
🪄 I turn CRM into a primary revenue channel - building lifecycle journeys and multi-channel campaigns that increase retention, repeat purchases, and LTV.
With 4+ years’ experience across the UK, US, Europe, and Asia, I design and optimise multi-channel CRM programs (email, SMS, push, onsite) that convert - from onboarding and activation to cross-sell, winback, and loyalty.
