As a Level 3 AI Data Labeler and Atlas Trainer in the Atlas Label Community, I completed annotation, classification, and AI response evaluation tasks across multiple projects. I evaluated AI-generated outputs for quality, factual accuracy, coherence, and instruction-following, gaining hands-on experience with RLHF-style review workflows. I applied detailed project-specific guidelines to flag edge cases and ambiguous items with clear rationale. • Progressed to high accuracy and performance, consistently above baseline standards. • Contributed to downstream label consistency through precision and adherence to instructions. • Excelled in quality assurance and content moderation for AI workflows. • Utilized remote collaboration and guideline compliance throughout multiple projects.
