Labeling Experience

Data Annotation Specialist (Contract)

Snorkel AITextClassification

As a Data Annotation Specialist at Appen / Telus International, I was responsible for annotating and labeling over 100,000 data points with high accuracy. I collaborated with data scientists to train multiple machine learning models and provided critical feedback for process improvements. I utilized Snorkel to implement advanced annotation techniques and maintained precise documentation throughout my work. • Ensured 99% accuracy following specific guidelines and quality standards. • Enabled a 20% faster annotation process through feedback and documentation. • Helped train 5 machine learning models achieving 97% precision and recall. • Reduced annotation time by 30% through efficient use of Snorkel.
