Freelancer Overview

I have a strong analytical background supported by a degree in Mathematics and experience handling large datasets in administrative and finance roles. My work involves data cleaning, standardisation, and ensuring high accuracy in Excel, which translates well into data labeling and annotation tasks that require precision and consistency. Working in regulated environments has also strengthened my ability to follow strict guidelines, maintain confidentiality, and apply consistent judgment. I am skilled at identifying patterns, categorising data, and maintaining structured records, enabling me to deliver high-quality labeled datasets for AI training.
