As a Life Sciences Research Linguist & Data Analyst at Welocalize, I curated complex English and French datasets for AI training in technical and medical domains. My responsibilities included reviewing data for accuracy, terminology consistency, and removing linguistic bias. I ensured a natural, human-like quality in localized AI model outputs. • Performed statistical analysis to remove bias from AI training data sets. • Focused on medical and technical datasets requiring strong attention to terminology and detail. • Exceeded weekly production targets by 15% while working in a remote, asynchronous environment. • Used CAT tools (Trados, XTM) and adhered to best practices in data annotation for translation/localization quality control.
