Work History
Lead Data Scientist
Hindustan Times Digital Streams
09.2024 - Current
- Engineered an advanced AI chatbot for HT Auto using Retrieval-Augmented Generation (RAG) pipelines with Large Language Models (LLMs), deploying BERT and Sentence-Transformers for deep semantic understanding and precise, context-aware responses, all orchestrated in a high-performance vector database.
- Developed a cutting-edge Loan Recommendation Engine: Architected and implemented a multiclass machine learning framework to match users with optimal loan providers, significantly boosting approval rates and delivering highly tailored financial solutions.
- Devised a fintech product propensity model leveraging user reading behaviors; harnessed semantic similarity techniques to finely tune targeting and optimize product inventory, resulting in more effective and data-driven product placements
Lead Data Scientist
