Ahreum H.

Senior Korean Linguist | Transcription & AI Data QA Specialist

I’m a native Korean linguist with over 13 years of experience in translation, proofreading, editing, and technical content. Since 2025, I have also worked on AI evaluation, transcription, annotation, and linguistic QA projects. My recent work includes reviewing AI-generated Korean content, checking transcription accuracy, identifying linguistic errors, and providing concise feedback based on project guidelines. I also have experience with speaker identification, timestamp alignment, structured annotation data, and MT post-editing. Before moving into AI-related projects, I worked for more than 11 years as an in-house translator and content planner, mainly on technical manuals, product guides, and published books. I work in Korean as my native language, with fluent Japanese and professional working English.
