Freelancer Overview

I have over 8 years of experience in data labeling and AI training data, specializing in annotating and reviewing text, image, and video datasets to ensure high accuracy and consistency. I began as a Data Labeling Associate, where I developed strong skills in classification, annotation, and quality checks while meeting strict project guidelines and deadlines. I later advanced to a Quality Analyst role, where I audit labeled data, identify errors and edge cases, and ensure datasets meet required standards before being used in machine learning models. What sets me apart is my ability to combine hands-on annotation expertise with quality assurance and team support. I have experience monitoring annotator performance, conducting calibration sessions, and training new team members to maintain alignment and improve overall output quality. My strong attention to detail, analytical thinking, and commitment to continuous improvement allow me to contribute not just to data accuracy, but to optimizing processes and enhancing the overall effectiveness of AI training pipelines.
