About

I’m a Data Scientist with 4+ years of experience building machine learning and AI solutions across customer analytics, predictive modeling, forecasting, optimization, and Generative AI. I work across the ML lifecycle—from problem definition and data analysis to feature engineering, model development, evaluation, and production deployment. A few examples of my work: • Built a production optimization engine that generated ~$2M in annual transportation savings using Mixed Integer Linear Programming (MILP) and Gurobi. • Developed an ensemble demand forecasting system using XGBoost and time-series methods, contributing ~$1M in annual operational savings. • Built customer segmentation and propensity models across 50,000+ retail outlets, increasing targeted campaign conversion from 15% to 22%. • Built and deployed a GPT-powered RAG platform using LangChain, embeddings, and prompt engineering, reducing analyst response time by ~60%. I’m particularly interested in problems involving prediction, customer analytics, personalization, experimentation, and AI-powered products. I enjoy working on problems where the goal is not just to build a model, but to define the right objective, features, evaluation metrics, and business outcome. My areas of focus include Machine Learning, customer analytics, predictive modeling, forecasting, optimization, Generative AI, LLM applications, and RAG. Skills: Python • SQL • Machine Learning • Statistical Modeling • Predictive Analytics • XGBoost • LightGBM • Deep Learning • Time Series Forecasting • A/B Testing & Experimentation • Customer Segmentation • Propensity Modeling • Optimization • NLP • Generative AI • LLMs • RAG • MLOps I’m interested in Data Science and Applied ML opportunities where I can work on high-impact products, own problems end-to-end, and build ML systems that reach real users. 📩 Contact: ayusht474@gmail.com
