Freelancer - Data Annotation, Transcription & Technical Writing
As a freelance Data Annotation Specialist, I executed large-scale image, audio, video, and text annotation projects for AI data pipelines. I applied bounding box and segmentation tags on images, created timestamped and speaker/scene labels on audio and video, and performed text NER and classification labeling, ensuring label consistency and data quality. I developed and maintained detailed annotation guidelines and conducted multiple rounds of QA with inter-annotator checks. • Provided clear and standardized image/object tags with bounding boxes and segmentation. • Delivered timestamped transcriptions and classification labels for audio, video, and text. • Authored technical documentation and review reports for project managers. • Managed simple data preprocessing and file organization.
