Freelancer Overview

I am an experienced AI Language Specialist and Lead Editor with a strong background in improving Large Language Models through high quality data annotation and linguistic evaluation. In my previous roles I have managed large-scale datasets, performed complex data labeling and conducted linguistic quality assurance to ensure the accuracy and relevance of AI generated content. My work on high priority localization projects for Google involved deep grammatical analysis including morphology and syntax. As a Transcriber and Lead Editor for a Google (YouTube) related project, I ensured the accurate localization and quality of YouTube related content while managing linguistic consistency.
