Freelancer Overview

I am a seasoned AI Training Data and Data Labeling Specialist with over 7 years of continuous experience evaluating and annotating multilingual data for machine learning applications. At RWS, I have served as a Trilingual Online Rater, enhancing the quality and accuracy of AI language models in French, Italian, and English. My work includes assessing the coherence, relevance, and fluency of model outputs, contributing to conversational AI development, dataset validation, and cross-lingual quality assurance. I have played a critical role in improving model performance for global platforms, thanks to my precision, linguistic expertise, and deep understanding of cultural context. What sets me apart is my unique combination of linguistic mastery, technical fluency, and a strong commitment to data integrity. With professional experience as an interpreter and customer support expert, I bring a keen eye for detail, a 4.9/5 client satisfaction rating, and proven GDPR compliance in handling sensitive data. My background also includes domain knowledge in healthcare, legal, and technical fields, making me well-suited for specialized data labeling tasks that require nuance, accuracy, and ethical handling of content.
