Data Annotation Specialist delivering pixel-perfect computer vision, NLP, and LiDAR/sensor fusion annotations with QA-first accuracy.
GhanaWhat I'm looking for
I’m a versatile, detail-oriented DataAnnotation Specialist with hands-on experience in Computer Vision (3D), LiDAR/Sensor Fusion, and Natural Language Processing (NLP). I focus on critical thinking and logical reasoning to produce accurate, high-quality labeled data.
I’ve delivered precise annotations for images, videos, and 3D datasets using industry-standard tools like CVAT and Labelbox. I also strengthen results through data cleaning, preprocessing, and dataset organization—then validate quality through QA and annotation standards.
In my DataLabeler role, I analyzed, categorized, and labeled large datasets, improving machine learning algorithm accuracy by 25%. I created and applied standardized annotation guidelines with cross-functional teams, reducing annotation errors by 20% and improving workflow efficiency by 30%.
Before annotation work, I built customer-focused and compliance-driven experience as a Customer Service Agent and a Private Insurance Relations Officer. I consistently maintained accuracy under high volume, improved scheduling and communication, and ensured records were complete and regulatory-compliant.
