Aug 2024 — Sep 2025Built churn models and retention analysis, then deployed chatbots and document automation that reduced operator workload and approval errors.
• Predictive Modeling: Churn model (82% ROC-AUC, Scikit-learn) on B2B/B2C/B2G data – retained ∼5% more subscribers in pilot. • Customer Analytics: Feature engineering (Pandas, SQL); churn driver analysis informing retention campaigns across all segments. • Process Automation: Built and deployed production-scale AI chatbots, cutting operator workload by ∼30%. • Document Intelligence: Automated verification/proofreading agents (Hugging Face NLP) – reduced errors by 60%, approval time 3 days → 1. • MLOps: Model monitoring (prediction drift, failure rates) for deployed AI services in production.
