What I'm looking for

I am looking for opportunities that foster growth, innovation, and collaboration in data analysis.

I am a dedicated Data Analyst with over two years of experience specializing in SQL, Python, and data visualization. My journey in data analysis has equipped me with a strong foundation in various domains, including telecom, finance, sales, and fleet management. I am passionate about leveraging data to drive insights and improve operational efficiencies.

During my tenure at Karooooo Management Company Pte Ltd, I successfully analyzed fleet performance data, optimizing routes and reducing operational costs through data-driven insights. My projects, such as the Telecom churn prediction at the University of Hyderabad, allowed me to develop machine learning models that accurately predict customer churn, enabling targeted retention strategies. I am committed to continuous learning and adapting to new technologies in the ever-evolving field of data analysis.
