No explicit data labeling, annotation, or AI-training duties were described in the resume for this period. Because the responsibilities were not clearly tied to language-training-at-scale or data annotation tasks, this entry is not treated as a valid data labeling experience. • Not explicitly involved in AI/data labeling • Primarily transaction and customer service • No tutoring or annotation tasks stated • No labeling tools or datasets mentioned
