# Gaurav Bhattacharjee on Tal

## Headline

Senior Data Scientist \| GenAI & LLM Applications \| ML & Recommendation Systems \| IIM Bangalore

## About

My foundation in data science is classical \- Python, SAS, statistical modelling, propensity models, segmentation, hypothesis testing\. The kind of work where you had to actually understand what you were doing because there were no pre\-trained models to bail one out\. That grounding still shapes how I think about machine learning problems, even when the tools look very different now\. More recently, I've built an explainable AI coaching system \(XGBoost \+ SHAP\) across 55 sales KPIs \- the goal was never just accuracy, but giving managers something they could actually act on the next morning\. That one became a US patent application and a Dell Dyuti Best Project\. Then a GraphSAGE recommender trained on 3\.6M\+ account\-product relationships\. Then LLM\-powered reporting pipelines, hybrid RAG systems, agentic account planning workflows that compressed hours of research into under a minute\. 10\+ years of machine learning across fraud detection, loyalty analytics, e\-commerce, media, and enterprise sales\.
