As an AI Operations Quality Analyst, I led the quality assurance reviews of large-scale annotated datasets to ensure accuracy and compliance. I enforced annotation standards and collaborated with cross-functional teams to resolve edge cases and ambiguity. I audited and approved datasets for model training while identifying potential bias or sensitive content. • Reviewed and improved inter-annotator agreement and labeling consistency. • Provided coaching, mentorship, and onboarding for junior annotators and QAs. • Used proprietary internal tools to audit, label, and support dataset readiness. • Monitored quality KPIs and balanced operational needs for speed, accuracy, and scale.
