Key Strengths

• Scaled ML/NLP data processing on 2B+ structured and unstructured records
• End-to-end customer segmentation + propensity modeling (K-means, logistic regression, random forest)
• Rigorous model selection/validation (elbow + silhouette, k-fold CV, ROC/AUC, precision/recall, F1/F4)
• Business-impact delivery: dashboards in Tableau/R Shiny and ~18% engagement efficiency improvement
• Entity resolution across multi-source customer data using hybrid matching + TF-IDF similarity with manual QA
• Built semantic search/data linking using SentenceBERT embeddings + vector database; ~20% relevance lift
• Production-grade workflow engineering (modular pipelines, logging, config, unit tests; Spark/cloud scaling)
• Pragmatic prototype-to-production decision-making with deployment via Docker/Azure ML
