Freelancer Overview

I’ve spent the last few months doing data annotation across text, images, and audio, mostly on NLP stuff like entity tagging, sentiment, and QA pairs. I’m pretty detail-obsessed and quick at picking up guidelines, plus I catch the weird edge cases that mess with models. I’ve worked with tools like Label box and Prodigy on large datasets, and I always make sure to log confusing cases so the team can actually fix the root problem.

Labeling Experience

Data Annotation Specialist (NLP Focus)

LabelboxTextEntity (NER) Classification

I performed data annotation on large datasets focused mainly on NLP tasks including entity tagging, sentiment analysis, and question answering pairs. I was responsible for carefully following guidelines, identifying edge cases, and maintaining clear records of confusing data instances for further team review. My work included labeling across text, images, and audio, but emphasized natural language tasks and accuracy in complex scenarios. • Labeled entities and sentiments in text corpora for AI model training • Applied quality control by logging ambiguous samples • Used tools like Labelbox and Prodigy for annotation tasks • Specialized in detecting edge cases that challenge model performance
