My Expertise in AI Data Annotation & QA
Computer Vision Labeling
I provide computer vision labeling services including bounding boxes, polygons, keypoints and semantic segmentation —helping AI models detect, classify, and localize objects in images with precision.
NLP Annotation
I offer NLP annotation services for AI, including text classification, sentiment analysis, audio-to-text transcription and named entity recognition—training models to understand and process natural language data.
Audio Annotation
I deliver audio annotation services such as speech transcription, noise labeling sound event detection, and emotion recognition in audio — powering machine learning models for speech AI and voice recognition systems.
A Bit About Me
I’m a remote Data Annotation Specialist with 12+ years of experience supporting AI and machine learning teams worldwide. I work across multiple annotation types — including image classification, segmentation, bounding boxes, polygons, text labeling, transcription, and audio annotation.
Over the years, I’ve built a strong sense for clean, high-quality data. ML engineers value my ability to maintain accuracy, follow complex guidelines, and spot subtle issues others miss — key strengths for data quality and accuracy verification work.
I frequently handle QA and consistency checks to ensure datasets are ready for computer vision labeling, AI image labeling, and precise text-based annotation. My approach is detail-oriented, context-aware, and focused on delivering reliable datasets for model training.
Outside of work, I enjoy cycling, nature, learning, and volunteering with animals — a balance that keeps me curious and focused in every project I take on.
“Andrea was an excellent data labeler, leading her group in labeling sentences for similarity. The task required careful attention to the task, and Andrea was able to work quickly and carefully.”
