Freelancer Overview

Detail-oriented Data Annotator and System Analyst with 4+ years of experience working across complex workflows, research, and quality-focused execution. I have hands-on experience labeling training data for AI models, specifically focused on detecting personal information (PII) in emails. I work accurately with sensitive data (names, SSNs, etc.), follow strict guidelines, and handle edge cases through strong contextual analysis. My background in SQL and Python helps me understand how data quality impacts model performance and improve annotation consistency. Education: Master of Science, St. Petersburg State University (2025); Bachelor of Science, St. Petersburg State University (2023).
