Key Skills

Freelancer Overview

I am an experienced AI training specialist and data annotator with over 4 years in high-volume, compliance-driven environments, working across computer vision, NLP, audio, e-commerce, and medical domains. My background includes leading annotation and QA for complex projects—producing and validating hundreds of thousands of image, text, and audio labels using tools like CVAT, Python, DVC, and SQL. I have developed and enforced annotation guidelines, built semi-automated pipelines, and implemented robust QA processes that improved accuracy, reduced disputes, and enhanced team efficiency. I am skilled in structured data validation, process documentation, inter-annotator agreement studies, and collaborating closely with ML engineers to optimize training data for better model performance. I thrive in remote, distributed teams and am committed to delivering high-integrity, reproducible datasets that drive AI innovation.
