Freelancer Overview

I am an experienced AI analyst and evaluator with over four years working on data-driven projects in AI, blockchain, and fintech. My background in scientific research (microbiology and molecular biology) gives me a systematic approach to evaluating data, identifying logical inconsistencies, and documenting edge cases in complex content systems. I have hands-on experience with data annotation, content quality analysis, and scenario assessment, using tools like Google Analytics, Hotjar, and Optimizely to evaluate user behavior and content performance. I excel at spotting ambiguities and inconsistencies in structured data, optimizing workflows, and ensuring logical consistency in AI outputs. My work has contributed to significant improvements in user engagement and conversion rates, and I am comfortable working with low-code automation platforms and structured content management systems. I am intellectually curious, detail-oriented, and thrive in remote, project-based environments that require critical thinking and clear documentation.

Image-Based Age Group Classification and Quality Assurance for AI Systems

AppenImageClassification
Worked on a project supporting computer vision AI systems by reviewing and labeling image data to classify human age groups based on visual guidelines. The scope of the project involved analyzing facial and physical features in images and assigning accurate age group labels while maintaining strict consistency across large datasets. Performed image-level classification tasks using predefined age categories, carefully following visual and quality guidelines to minimize bias and labeling errors. Reviewed edge cases where age estimation was ambiguous and applied standardized decision rules to ensure labeling accuracy and reliability. Participated in quality assurance processes by double-checking annotations, identifying inconsistencies, and correcting misclassified samples. Adhered to project accuracy thresholds, review standards, and audit requirements to maintain high-quality labeled data suitable for training and evaluating AI models.
