Hi, I’m Christian Onwuai. I am a detail-oriented AI data labeler and annotator with hands-on experience labeling image, text, and audio data for machine learning and AI training projects across platforms including Telus Digital and Lionbridge. I follow complex labeling guidelines to maintain high accuracy and consistent quality across large data sets.
I excel at identifying edge cases, evaluating AI outputs for relevance, safety, and cultural appropriateness, and providing precise feedback to improve model performance. I thrive in remote teams, stay deadline-driven, and bring reliability, analytical thinking, and fast turnaround to every labeling task.
