I evaluated Chinese-to-Korean machine translations for accuracy, fluency, and naturalness, identifying mistranslations and issues with meaning or context against project-specific guidelines.

As a freelance AI Speech Data Contributor & Evaluator, I recorded Korean speech samples and reviewed audio for pronunciation, intonation, fluency, naturalness, and background noise.

At Preply, I teach Korean to international learners at different proficiency levels. I explain grammar, vocabulary, pronunciation, and everyday expressions, including the difference between grammatically correct and natural Korean.

I studied Chinese Language at Dalian University of Foreign Languages and have advanced Chinese proficiency (HSK 6: 259/300), with approximately 10 years of living experience in China.
