About

I’m a Data Scientist with ~2.5 years of experience building data-driven solutions across demand forecasting, machine learning, and analytics. My work focuses on solving real-world business problems using predictive modeling and time series techniques. I’ve developed and deployed models for complex demand patterns (smooth, erratic, intermittent, and lumpy), leveraging feature engineering approaches like ADI and CV² to improve forecast accuracy and reliability. With a foundation in software development, I bring a strong understanding of data pipelines, scalability, and production systems allowing me to go beyond modeling and contribute across the full lifecycle from data exploration to deployment. Key areas of expertise: Time Series Forecasting (ARIMA, ensemble models, intermittent demand techniques) Machine Learning & Predictive Modeling Feature Engineering & Data Analysis Python, SQL, and scalable data workflows I’m particularly interested in building robust ML systems that drive business decisions and continuously improve through data.
