NigeriaWhat I'm looking for
I am a detail-oriented AI data specialist and freelance photo data collector with extensive experience capturing, annotating, and validating real-world images and video for visual AI training. I consistently deliver high-accuracy contributions (98–99%) across large-scale projects with platforms like Luma, Scale AI, Appen, and Micro1, focusing on authenticity, metadata compliance, and instruction adherence.
I have annotated and validated 100,000+ images, performed side-by-side text-to-image evaluations, and implemented rigorous quality-assurance processes that improved generative model reliability. I thrive in remote freelance environments and am eager to apply my photography, annotation, and validation skills to collect authentic real-world images for next-generation visual AI systems.
