What I'm looking for

I seek a role labeling and preparing high-quality datasets for ML, collaborating with QA, using modern annotation tools, and growing in data-quality responsibilities.

I am a detail-oriented Data Annotation Specialist with hands-on experience in image tagging, text classification, named entity recognition, and audio transcription, focused on producing high-quality labeled data for machine learning models.

I have performed sentiment analysis on 100+ social media comments, collaborated with QA leads to resolve labeling ambiguities, and consistently met production quotas while maintaining strong accuracy standards.

I bring practical experience with Labelbox, Amazon SageMaker Ground Truth, Scale AI, Excel/Sheets, basic Python for data handling, and a commitment to data privacy and reliability to improve AI model performance.
