GOPI A User

I am a Senior Data Annotator with over four years of hands-on experience labeling and annotating large datasets to support machine learning initiatives. I have annotated and labeled over 100,000 data points with 99% accuracy using tools such as Snorkel and Labelbox, and I collaborate closely with data scientists and engineering teams to improve model outcomes.

My contributions include providing actionable feedback on annotation guidelines that accelerated the annotation process by 20% and implementing techniques that reduced labeling time by 30%. I have supported the training of multiple ML models that achieved precision metrics of 95–97% and maintained meticulous documentation that cut annotation errors by 50%.

I stay current with annotation best practices and tooling, assist in model training, and help improve annotation tools and workflows to drive efficiency and model quality. I communicate consistently with cross-functional teams and focus on delivering reliable, high-quality data for production ML systems.
