about

I’m a data analyst and AI trainer with 3+ years of experience in data annotation, LLM evaluation, and prompt engineering. I annotate image and video datasets using bounding boxes, polygons, and keypoints, and transcribe and timestamp audio with background-noise labeling. I evaluate and rank AI responses for accuracy, safety, and helpfulness, identify subtle errors and edge cases, and provide structured feedback to improve model quality. I also design context-aware prompt templates, enforce output formatting and tone, and refine token usage to reduce latency and computational costs. My data analysis experience includes statistical analysis, trend and anomaly detection, collaboration with engineering teams on automated data tracking, and recommendations that support budget allocation and operational efficiency.
