Freelancer Overview

I am a detail-oriented professional with a strong background in data analysis, automation, and data management, supported by an MSc in Applied AI & Data Analytics. My experience includes developing and automating R scripts to optimize data extraction and transformation, significantly reducing manual workloads and improving data accuracy in large-scale occupational exposure limit (OEL) datasets. I have performed thorough data audits, validated database integrity, and ensured seamless integration of new data sources, contributing to faster project turnaround and enhanced data reliability. Proficient in SQL, R, and dashboard creation, I bring a proven ability to streamline data handling processes, maintain high-quality annotated datasets, and support AI training data initiatives across technical and operational domains. My collaborative approach and commitment to data quality make me well-suited for roles in data labeling, annotation, and AI-driven projects.
