Labeling Experience

Labelbox

Data Annotation & Labelling Specialist (Freelance/Remote)

LabelboxLabelboxTextTextFine-tuningFine-tuning

Prepared NLP datasets for text classification, sentiment tagging, and LLM fine-tuning pipelines using structured labeling frameworks. Ensured labels conformed to defined annotation guidelines and targeted consistent data representations for training. Coordinated with technical stakeholders by flagging edge cases and ensuring the stability of labeling ontology for large-scale annotation batches. • Built and validated text/NLP labels for classification and sentiment tasks. • Applied structured labeling frameworks to support LLM fine-tuning workflows. • Ensured annotation guideline compliance and cross-annotator alignment. • Escalated ambiguous samples to maintain ontology integrity.
