Gautam Kumar

I’m a B.Tech graduate (CSE - AI & ML) focused on using data science to deliver real, practical outcomes. I bring hands-on experience applying Python, SQL, and machine learning techniques through internships and academic projects.

In my Data Analytics Intern role, I used SQL (joins, subqueries, aggregations) to analyze 5,000+ records and surface insights for stakeholders. I also cleaned, transformed, and engineered features on 10,000+ records with Python (Pandas, NumPy), and I designed Power BI dashboards that reduced manual report preparation time by 40%.

Across projects, I built an automated ML-driven data cleaning and pre-processing pipeline using Pandas and Scikit-learn for datasets exceeding 10,000 rows, cutting manual preprocessing effort by 60%. I’ve also performed churn prediction and analysis on 7,043 telecom customers (feature engineering, 11 visualizations) and completed e-commerce sales analysis with advanced SQL (joins, aggregate functions, window functions), always aiming to translate data into actionable business insights.
