Stephanie Okoye

I am a detail-oriented AI data specialist with practical experience in data collection, annotation, labeling, and quality assurance across text, image, audio, and video. I deliver accurate, high-quality results on flexible schedules and excel at remote collaboration.

In freelance AI and data projects I conducted annotation and labeling for multimodal datasets, performed pairwise comparisons and evaluations to improve AI-generated content, and contributed to data preprocessing and structuring for ML training.

As a database administrator at a cloud computing company, I manage, maintain, and optimize database systems, perform extraction, transformation, and validation tasks supporting business intelligence, and collaborate to ensure data accuracy and compliance across environments.

I hold a B.Sc. in Pharmacy and completed training in SQL & Database Management (Advanced), Python for Data Analysis (Intermediate), and Machine Learning Foundations; I bring strong English proficiency (C1/C2) and a focus on attention to detail and data integrity.
