Freelancer Overview

I am a computer science professional with over four years of specialized experience in AI evaluation, data annotation, and quality assurance for large language models. My background includes designing and labeling challenging, real-world datasets across domains such as cybersecurity, adversarial testing, and structured problem evaluation. I have a strong foundation in CS fundamentals, including algorithms and data structures, and I excel at identifying edge cases, logical inconsistencies, and subtle data quality issues that automated systems often miss. My technical skills include prompt engineering, model behavior analysis, and structured data analysis using tools like Python, JSON, and Git. I am adept at collaborating remotely with distributed teams, maintaining rigorous quality standards, and providing actionable feedback to improve AI system performance. My work is driven by attention to detail, critical thinking, and a commitment to ensuring data accuracy and reliability in high-stakes environments.
