Freelancer Overview

I am an analytical professional with a strong background in data validation, quality control, and structured data management, particularly within healthcare and scientific domains. My experience at the CDC has equipped me with the ability to review, annotate, and validate complex technical content, ensuring data accuracy and compliance in highly regulated environments. I excel at identifying discrepancies, enforcing consistency, and applying strict SOPs—skills directly relevant to data labeling, annotation, and AI training data tasks. My technical toolkit includes Microsoft Excel, introductory SQL and Python, and experience with Laboratory Information Systems, enabling me to handle large datasets with precision. I bring a high level of attention to detail, process discipline, and a quality-first mindset to every project, making me well-suited for roles that require reliable, audit-ready data for AI and machine learning workflows.
