Key Skills

Freelancer Overview

I have experience working with structured and unstructured data, including text annotation, transcription cleanup, content categorization, data validation, and quality assurance tasks that support AI model training and evaluation. My background as a software consultant and developer has given me strong analytical skills, attention to detail, and the ability to follow complex annotation guidelines consistently. I am comfortable working with large datasets, identifying inconsistencies, maintaining labeling accuracy, and documenting edge cases to ensure high-quality training data. In addition, I have extensive experience reviewing written content, validating outputs against predefined standards, and working with technologies such as JavaScript, React, SharePoint, and business applications, which helps me understand both technical and non-technical datasets. My combination of technical expertise, problem-solving ability, fast learning, and commitment to quality enables me to contribute effectively to AI training, data annotation, transcription, content moderation, and human-feedback evaluation projects.
