AI Evaluator at Handshake AI who annotated image and video datasets and evaluated real-time AI audio outputs.

At Handshake AI, I annotated image and video datasets for computer vision models and evaluated real-time sound-to-sound AI outputs for latency, acoustic clarity, pitch, and contextual responsiveness. I also checked guideline compliance across data pipelines.

At Atlas Capture AI, I annotated text and multimodal datasets and used spreadsheets and Python for data research and script processing. Earlier, at Appen (CrowdGen), I assessed LLM responses for relevance, factual consistency, and alignment with human intent.
