I’m Rohith 👋, a passionate and results-driven data scientist with a strong focus on machine learning 🤖 and advanced analytics 📊. I am currently working as a Senior Analyst at Nestlé USA, where I leverage data science to drive actionable insights and optimize business processes. My expertise spans sales and marketing analytics, supply chain optimization, consumer insights, and product performance analysis 🔍.

Previously, I worked as a Research Assistant 👨‍🔬 in Machine Learning at Montclair State University, developing sophisticated models for malware detection in npm packages. I also contributed at BYJU'S, where I helped improve student engagement and outcomes through data-driven decision-making 📈. At Enercast GmbH, I applied advanced ML techniques to enhance renewable energy forecasting ☀️.

I hold a Master’s degree in Data Science from Montclair State University 🎓. My technical toolkit includes Python 🐍, SQL, cloud technologies ☁️, and machine learning frameworks such as Scikit-Learn, TensorFlow, and XGBoost.

In addition to hands-on experience, I’ve earned several industry-recognized certifications that reflect my commitment to continuous learning and technical excellence:
