I help B2B SaaS and product teams ship faster by reducing communication friction. Nine years across Indonesia, Germany, and Japan taught me to ship across cultures without slowing down. I've built UX copy systems and content strategy for teams at scale, from onboarding to product announcements to internal alignment. What I deliver: → UX copy and microcopy that doesn't need rework (you ship first, not fifth) → Content strategy that connects product clarity to user adoption → Cross-team alignment on messaging (less back-and-forth, faster decisions) → Practical documentation and content systems teams can maintain Some results: • Reduced feature announcement revision cycles from 8 rounds to 2 for a product team (40% faster to ship) • Built onboarding flows that improved user completion by 35% through clearer language alone • Restructured product docs that became the source of truth across 3 departments (reduced redundant communication) • Rapid content iteration for teams shipping across Japan, Germany, and English-speaking markets Tools & methods: UX writing systems, content audits, multilingual product strategy, AI-assisted research (not replacement), Figma, documentation systems, cross-functional alignment workshops. I work with international product teams who need to ship fast without rework. Fluent in English and Indonesian, functional in Japanese and German, so I adapt messaging across markets and cultures without slowing you down. If you need someone who can lead UX strategy end to end, from onboarding to product announcements to team alignment, let's talk.
