Freelancer Overview

I am a professional data labeler with extensive experience supporting AI training projects, particularly for Large Language Models. I have worked on prompt creation, data annotation, evaluation, and internal auditing for multiple international companies, including Telus, Welo Data, RWS, Appen, and Alignerr. My strong analytical skills, attention to detail, and critical evaluation abilities enable me to manage complex data and ensure high-quality results. I am proficient in written English (CEFR C1), comfortable with key digital tools, and have a background in linguistics, which enhances my effectiveness in natural language processing tasks. I am highly motivated, adaptable, and eager to take on new challenges in emerging fields.
