Freelancer Overview

I have hands-on experience in data annotation and AI training data, having worked as a Data Annotator where I analyzed and labeled large-scale datasets with a 98% accuracy rate. My role involved developing quality assurance protocols and using data monitoring tools to improve annotation consistency and workflow efficiency. I have collaborated closely with AI engineering teams to refine annotation guidelines and optimize processes, directly contributing to enhanced machine learning model performance. My technical background in computer science, combined with strong skills in data structures, SQL, and agile methodologies, enables me to deliver high-quality, reliable training data for AI projects. I am adept at working in fast-paced, cross-functional environments and am committed to maintaining high standards of data quality and integrity.
