Freelancer Overview

I have hands-on experience contributing to AI training data through accurate data labeling, annotation, and quality review across multiple task types. My work includes text classification, sentiment analysis, entity recognition, content moderation, and prompt–response evaluation, where precision and consistency are essential. I am comfortable following detailed annotation guidelines, adapting quickly to new task instructions, and maintaining high accuracy under tight deadlines. What sets me apart is my strong attention to detail, analytical thinking, and reliability in delivering clean, well-structured datasets that directly improve model performance. I understand how high-quality annotations influence model behavior, bias reduction, and overall AI reliability. With a background in digital tools, remote collaboration, and fast learning, I consistently meet quality benchmarks while scaling across diverse data domains and AI training objectives.

Video Labeller

I worked on a sports video labeling project covering the 2021–2022 English Premier League season, focused on annotating 12 full-match football videos for AI training purposes. The scope included temporal event labeling such as goals, shots on target, passes, fouls, offsides, set pieces, substitutions, and ball possession changes, as well as player and team identification during key sequences. Annotations were performed using frame-accurate tools and predefined taxonomies to ensure consistency across matches. Quality was maintained through strict adherence to annotation guidelines, timestamp precision checks, and multi-pass reviews of labelled segments. Each video underwent self-review and peer validation to minimize missed events and misclassifications, with feedback loops used to correct inconsistencies. Accuracy, consistency, and completeness were the primary quality metrics, ensuring the dataset was reliable for downstream sports analytics and computer vision models.
