Freelancer Overview

Data Annotation and AI Quality Assurance Specialist with two years of experience labeling, auditing, and optimizing datasets for machine learning models. Practical background includes managing large-scale text classification, multi-modal verification, and Reinforcement Learning from Human Feedback (RLHF) tasks. Experienced in working with strict quality rubrics, identifying edge cases, and delivering highly accurate ground truth data across remote, self-paced production environments.

Labeling Experience

AI Image Quality & Instructor

ImageEvaluation/Rating

Evaluated and optimized multimodal AI models on Project Aether via Outlier, focusing on image-to-text alignment and visual quality assurance. Key responsibilities included: • Conducting rigorous quality control to identify and filter out visual anomalies, rendering errors, and characteristic "AI slop/artifacts." • Assessing whether model-generated images precisely adhered to complex, multi-layered user prompt instructions. • Evaluating image-to-image consistency and ensuring high-fidelity visual alignment with source criteria. • Providing detailed, objective feedback and data tagging to refine the realism and accuracy of generative AI image models.
