WORK EXPERIENCE:

Data Scientist/Machine Learning Engineer

Confidential, Santa Clara, CA

Responsibilities:

  • Object identification and logo recognition in household images (AWS Marketplace model packages: GluonCV YOLOv3 and Sensifai)
  • Automated parsing of PDF forms to extract key-value pairs/Named Entity Recognition (AWS Textract, Spacy)
  • Call volume forecasting for customer service center (LSTM Sequence to sequence); Monitor news stories and associated sentiment to predict impact of external events (data breaches, natural calamities, etc.) on call volume to optimize call routing, resource scheduling and prepare response strategy
  • Topic clustering/classification and sentiment analysis to summarize and obtain actionable insights into customer complaints/reviews (LDA2Vec, Natural Language Toolkit, Spacy)
  • Real-time anomalous topic detection based on call/chat transcripts (LSTM)
  • Recommendation engine for prediction of customer problems and possible solutions based on customer’s geo-demographic data and interaction history (Random Forest, Gradient Boosting)
