Freelancer Overview

From January 2026 to March 2026, I served as a Data Labeling Associate with Outlier AI where I had hands-on experience annotating text and image datasets to create training data for machine learning models. The bulk of my time was spent classifying, tagging, and annotating bounding boxes per established annotation guidelines while maintaining consistency and accuracy. I performed data validation and quality checks to identify labeling errors. I collaborated with reviewers to improve dataset quality and model performance. My Computer Applications background has prepared me for working with structured data, and I am proficient in using annotation tools like CVAT and LabelImg as well as Excel and Python (basic) for managing data. I possess qualities such as attention to detail, meeting productivity goals, and a strong commitment to quality assurance that distinguish me as an ideal candidate for AI training and data annotation positions.

Labeling Experience

As a Data Labeling Associate at Outlier AI, I labeled and annotated both text and image datasets to train and evaluate AI models. My role demanded a strict adherence to annotation guidelines while ensuring data quality and consistency. I collaborated with AI trainers to improve labeling accuracy and routinely conducted validation checks. • Labeled datasets using classification, tagging, and bounding box methods • Utilized CVAT, LabelImg, and Label Studio extensively for image and text annotation • Performed quality assurance checks and corrected labeling errors to enhance model outputs • Worked under productivity targets and improved processes through feedback collaboration
