Freelancer Overview

‎I have worked with leading platforms like Outlier, Aligner, Invisible AI, and Telus International to improve AI models through data labeling and training. My daily work involves writing original content in English and French, creating short stories to boost model creativity, and ranking AI responses to ensure they are helpful and well-structured. As well as optimizing online search quality by evaluating content relevance and auditing results for grammatical accuracy, appropriate tone, and cultural alignment. ‎What sets me apart is my ability to ensure factual accuracy. I don't just label data; I carefully audit AI-generated text to catch errors and ensure the information is reliable. With my experience across multiple companies, I am highly adaptable and efficient at delivering the high-quality data needed to build smarter, safer AI.
