Freelancer Overview

I am an experienced Data Scientist with over 4+ years of hands-on experience working across data preparation, labeling workflows, and AI training data validation, particularly in computer vision and machine learning projects. My work has involved image annotation, classification tasks, quality checks, and dataset validation as part of building and testing object detection, defect classification, and video analytics models. I have worked with annotation tools such as CVAT and Azure Custom Vision, ensuring high accuracy and consistency in labeled datasets used for production-grade AI systems. What sets me apart is my strong understanding of how high-quality training data directly impacts model performance. Having contributed to end-to-end ML pipelines—from data annotation and feature engineering to model testing and benchmarking—I bring both a data quality mindset and technical depth to AI training data projects. I am detail-oriented, comfortable working independently, and experienced in collaborating with cross-functional teams to deliver reliable, scalable, and high-accuracy datasets that support advanced AI applications.
