About
I’m Vonna Foster Lyons, a detail-oriented AI data annotator, trainer, and reviewer with 4+ years of experience improving machine learning and LLM performance. I work across image/video labeling, bounding box and object detection, and large-scale dataset QA to help teams build reliable, human-centered AI systems.
I’ve also trained and evaluated AI/LLM outputs for accuracy, clarity, safety, and instruction adherence designing prompts and edge-case tests, auditing labeled data for consistency, and documenting improvements to reduce error rates. I’m known for meeting throughput targets while maintaining strong quality standards and using thorough error analysis to strengthen model outcomes.
