ImageClassification

I execute high-priority image and video annotation tasks to support generative AI models in Arts & Design domains. My work ensures factual correctness, safety, and creative constraint alignment in AI outputs. I also calibrate annotation standards with QA teams to reduce ambiguity. • Multimodal annotation expertise including images and video. • Fact-checking and creative evaluation of generative AI outputs. • Collaboration with quality assurance for standardization. • Task management using proprietary internal platforms.
