Freelancer Overview

I am a detail-oriented AI training and data quality specialist with over 7 years of experience in human evaluation, data labeling, and quality assurance for large-scale machine learning projects. My background includes reviewing and validating complex datasets, developing annotation guidelines, and providing actionable feedback to ensure data accuracy and consistency. I have a strong track record of mentoring contributors, identifying edge cases, and collaborating with cross-functional teams to improve AI model performance. My skills in instruction-following evaluation, written documentation, and digital research have enabled me to support projects aligned with high standards of data quality and safety, particularly in NLP and digital research domains. I am fluent in English and Swahili, and thrive in roles that require analytical thinking, clear communication, and a commitment to continuous improvement.
