Freelancer Overview

I am computer Science graduate with hands-on experience in AI data annotation, machine learning dataset evaluation, and quality assurance for AI systems. Proven ability to assess data accuracy, enforce annotation standards, identify inconsistencies, and deliver high-quality labeled outputs against strict quality thresholds. Comfortable working independently in remote, asynchronous, project-based environments.

Labeling Experience

AI Data Annotation & Model Evaluation

AppenTextPoint Key PointEntity Ner Classification

Reviewed and annotated large datasets used for training and evaluating machine learning and AI systems. Assessed model outputs for accuracy, consistency, tone, and logical alignment with detailed annotation guidelines. Identified ambiguous and edge-case samples, escalating inconsistencies in task instructions to maintain data quality. Applied structured judgment to label complex and nuanced content, consistently meeting strict quality thresholds. Delivered all work independently in an asynchronous, remote, project-based environment with minimal supervision
