About

I once had to explain “What is AI?” in a school assembly. That curiosity eventually turned into a career where I now work at the intersection of Data Science, Machine Learning, Business and Analytics. In my current role, I work across the full data lifecycle—from building data pipelines and performing business analysis to developing machine learning models and intelligent analytics solutions. My work focuses on solving real business problems such as pricing anomalies, demand forecasting, customer segmentation, and recommendation systems. Using Python, SQL, Power BI, and machine learning frameworks, I build data products that automate reporting pipelines (saving 100+ hours per month), generate actionable insights, and support data-driven decision-making for leadership teams. Beyond work, I host podcasts with data professionals, teach data science to students and working professionals, and enjoy sharing insights about machine learning, coding, and careers in data. Always curious, always learning, and always open to collaborating on ideas where data and AI can create real-world impact.
