Freelancer Overview

I have experience in AI data labeling and annotation through my work with TELUS International AI, where I annotated and categorized over 15,000 images used to train machine learning models. My responsibilities included labeling visual data according to detailed guidelines, conducting quality assurance reviews, identifying and correcting inconsistencies and collaborating with project teams to ensure annotation standards aligned with evolving model requirements. Through this work, I maintained an annotation accuracy rate of 98%, contributing to improved model performance. In addition, my transcription experience with TranscribeMe and Rev.com strengthened my attention to detail, data quality management and ability to follow complex guidelines. These roles involved accurately processing large volumes of audio and text data, performing quality checks and handling sensitive information, skills that directly support AI training, data labeling and data validation projects.
