AudioTranscriptionAnnotated audio data for AI training pipelines with transcription, diarization, and timestamps. Completed speaker diarization and verbatim transcription with consistent timestamping for model-ready datasets. Achieved an average accuracy score of 98.5% across 200+ hours of audio content. • Speaker diarization • Verbatim transcription • Timestamping • Accuracy-focused quality assurance
ImageBounding BoxGenerated computer vision annotations to train AI/ML models using supervised labeling formats. Labeled objects with bounding boxes, polygon segmentation, and keypoints/pose-style annotations for downstream training. Maintained a <2% error rate through self-QA, project review, and consistency checks. • Bounding box annotation for detection training • Polygon segmentation for semantic/instance tasks • Keypoint labeling for pose/keypoint estimation • Self-QA and project review for accuracy control
TextEntity (NER) ClassificationProduced NLP training labels for conversational and long-form text datasets to support model fine-tuning. Applied named entity recognition (NER) tagging, intent classification, and sentiment labeling according to project style guides. Performed quality checks and inter-annotator agreement (IAA) reviews to flag inconsistencies for resolution. • NER entity tagging for entity extraction • Intent and sentiment classification for dialogue/text • IAA review to align labeling decisions • Structured QA and submission workflow
