Stephanie Okoye

I am a detail-oriented AI Data Specialist with hands-on experience in data collection, annotation, labeling, and quality assurance across text, image, audio, and video. I have delivered high-accuracy preprocessing and dataset structuring for machine learning pipelines while maintaining strict adherence to project guidelines and schedules.

As a freelancer and database administrator, I have performed pairwise comparisons and evaluations to improve AI-generated content quality and ensured data integrity by identifying and correcting inconsistencies. I have strengthened my technical foundation in SQL, Linux, and data-driven workflows to support business intelligence and analytics.

I hold a B.Sc. in Pharmacy and have completed certifications in SQL & Database Management, Python for Data Analysis, and Machine Learning Foundations. I bring strong English proficiency (C2), remote collaboration experience, and a commitment to producing reliable, high-quality data for AI model improvement.
