I’m an analytical, results-driven Data Analyst with hands-on experience transforming large datasets (10,000–50,000+ records) into actionable business insights using Excel, SQL, and Tableau. I focus on cleaning, validating, and structuring data so it’s trustworthy for decision-making.

In my SQL project, Customer & Sales Performance Analysis, I analyzed structured relational sales data to evaluate customer performance and revenue contribution. I used SQL (JOIN, GROUP BY, HAVING, Window Functions) to identify high-performing customer segments and extracted and validated multi-table datasets to uncover revenue drivers and performance trends.

In Excel, my U.S. Public Debt Trend Analysis built a structured financial tracker to evaluate long-term patterns. I cleaned and transformed historical datasets using Pivot Tables, XLOOKUP, INDEX/MATCH, and FORECAST.ETS, then built dynamic dashboards to identify growth trends and generate macro-level insights.

With Tableau, my Global Happiness Dashboard delivered an interactive view of international socioeconomic indicators. I created visualizations comparing GDP, social support, and happiness metrics across countries and enabled cross-country analysis using interactive filters and KPI views.
