What I'm looking for

I’m looking for remote, guideline-driven AI annotation work where accuracy matters most. I want to apply my Mandarin depth, fact-checking, and content safety skills to label, compare, and flag responses consistently across projects.

I’m a multilingual content specialist and data quality reviewer with over 4 years of professional experience in translation, cross-lingual content review, and written language quality assessment. I bring professional-level Mandarin (Chinese) proficiency alongside C2 English, with Korean and Spanish, so I can annotate and evaluate AI-generated content with precision and cultural sensitivity.

At Oneforma (2020–Present) and Prestige Global (2020–2022), I’ve reviewed large volumes of text and machine-generated outputs, applied detailed annotation guidelines, compared side-by-side responses, and flagged material that was factually incorrect, sensitive, ambiguous, or below quality thresholds. I’m trained to verify claims in legal, medical, and technical domains, and I maintain high accuracy in remote, asynchronous, high-volume workflows using tools like SDL Trados Studio and MemoQ.
