What I'm looking for
I am a detail-oriented and tech-savvy professional with hands-on experience in data annotation and AI model training support. My proven ability to accurately label, categorize, and process large datasets with speed and precision has been instrumental in my freelance work. I have annotated over 50,000 images and videos for various datasets, utilizing platforms like Labelbox and CVAT. My commitment to ensuring data quality and model accuracy is reflected in my collaboration with QA teams to improve annotation consistency.
With a Bachelor of Technology in Building and Construction Technology from Moi University, I have supplemented my education with certifications in Data Annotation and Artificial Intelligence. My project highlights include annotating images for autonomous driving datasets and classifying product categories for an AI search engine. I thrive in team environments and am dedicated to maintaining high standards of confidentiality and data security.
