What I'm looking for

I’m looking for a role where I can build SQL and Python-driven analytics, improve query/database work, and turn datasets into Power BI dashboards and clear, actionable insights.

I’m working through data analysis projects that turn raw match and sales data into interactive dashboards—most recently a FIFA World Cup 2026 analytics dashboard using Python (Pandas), SQL, DAX, and Power BI.

In internships at DRDO and Celebal Technologies, I worked on network security concepts like OSI model layers and TLS/SSL protocols, and I also developed and optimized SQL queries for efficient retrieval and database management.

I use Python, SQL, Excel, Pandas, NumPy, Matplotlib, and Seaborn for data cleaning, exploratory data analysis, visualization, and business reporting, then package it into dashboards with Power BI.
