Freelancer Overview

I am an AI training and language quality specialist with over 10 years of experience in translation, localization, and editorial operations, with a strong focus on data labeling, annotation, and NLP tasks. My hands-on background includes evaluating machine translation output, annotating linguistic errors, conducting document labeling, and performing sentiment, tone, and semantic consistency reviews. I have managed human-in-the-loop QA processes, developed repeatable quality systems, and built annotation guidelines for both text and multimedia content. My expertise also covers transcription, speech-to-text review, and audio labeling, alongside deep familiarity with tools like JIRA, Confluence, memoQ, Trados, and XBench. I excel at translating complex quality findings into actionable feedback for product, engineering, and operations teams, ensuring high standards in AI model training and data quality across diverse domains.
