Detail-oriented AI data annotator specializing in high-accuracy labeling for ML training.
What I'm looking for
I am a detail-oriented AI Data Annotator with hands-on experience labeling text, image, and video datasets for machine learning platforms such as Remotasks and Mindrift. I consistently follow strict guidelines to deliver accurate, high-quality annotations and review errors to preserve data integrity.
My background includes customer-facing and technical roles — from IT support at BT Group to customer support at Tesco — which strengthened my troubleshooting, communication, and process-improvement skills. I collaborate effectively with international remote teams to refine task instructions and improve workflows.
I hold a BSc in Information Technology from the University of Manchester and bring a proven track record of reliability, meeting deadlines, and maintaining quality under pressure; I seek to apply these strengths to impactful data annotation and quality assurance projects.
