Data Engineer – Data Labeling & AI Model Training
As a Data Engineer at Excel IT CORP, I enriched a normalized review corpus with sentiment and topic tags via scikit-learn and a fine-tuned LLM in PyTorch. My labeling efforts supported AI model training for enterprise analytics. This role required systematic tagging and classification of text data for improved sentiment analysis and topic modeling. • Labeled review text data for sentiment and topics. • Utilized machine learning and LLM tools for data annotation and enrichment. • Ensured consistency and validity of tagged data for downstream training. • Integrated labeled data into reporting systems.
