Transforming raw data into smart decisions.

About Me

I'm Navpreet Singh, a data analyst with a sharp eye for patterns and a passion for storytelling through numbers. I hold a Master's degree in Data Science and Analytics from Maynooth University and bring hands-on experience turning raw data into actionable insights across multiple industries. From building predictive models and automating dashboards at AppTesters to crafting data-driven solutions for operational risk at Defloors, I've consistently delivered results that drive smarter decisions. My technical toolkit includes Python, SQL, Power BI, Tableau, and machine learning, while my strength lies in bridging the gap between data and real-world impact. Whether it's forecasting retail sales, analyzing accident patterns, or creating AI-powered recommendation systems, I combine analytical precision with creativity to turn data into strategy. I don't just analyze data - I make it work for you.
