About
I am Jaskar Jeyabalan, a B.Sc. in Computer Science graduate from The Madurai Diraviyam Thayumanavar Hindu College, completed in 2024. During my studies, I gained 8 months of internship experience in data science, working on projects such as sales forecasting, customer transaction prediction, and churn analysis. My strongest skills include SQL (Microsoft SQL Server, MySQL, MongoDB), Python (Pandas, NumPy, Scikit-learn), Power BI, and data visualization. I am seeking my first full-time role as a Data Analyst, where I can leverage my technical skills and analytical mindset to deliver actionable insights.
