Data Annotator / QA Specialist

TelusTextClassification

As a Data Annotator and QA Specialist at TELUS International AI, I was responsible for annotating and categorizing large-scale datasets using predefined taxonomies and structured guidelines. I performed side-by-side evaluations and fact-checked AI-generated outputs to ensure accuracy and consistency in model performance. I documented findings, flagged edge cases, and produced structured justifications to support evaluation decisions. • Applied annotation frameworks consistently across high-volume data labeling tasks. • Conducted quality assurance by reviewing logical consistency and relevance of outputs. • Flagged inaccuracies and inconsistencies for model improvement. • Ensured compliance with annotation standards during remote work.
