At Labelbox, I coordinated communication between Korean data labelers and English-speaking Project Managers, and helped build and lead a 200+ member Korean team. For an Amazon project, I worked across evaluator, coordinator, and reviewer tasks to support delivery of approximately 17,000+ deliverables.

At Mercor (Deeptune), I reviewed AI agent performance on complex, multi-step tasks and maintained 90%+ accuracy in data review and quality assurance. I’ve also taught English and used AI tools to support ESL students, and I bring native-level Korean and English fluency to cross-cultural work.
