What I'm looking for

I'm looking for a professional data analytics role where I can use SQL, Excel, and Power BI to build dashboards, deliver actionable insights, and support data-driven business decisions.

I've built end-to-end sales and customer analytics projects using MySQL, Excel, and Power BI to turn raw data into practical business insights.

In my Business Performance & Customer Analytics project, I designed a relational database with customer, product, and order tables, developed SQL views, and connected MySQL with Power BI for dynamic reporting. I created interactive dashboards covering sales trends, customer segmentation, product performance, customer lifetime value, retention, activity status, and business KPIs.

For a Sales & Customer Analytics Dashboard, I cleaned and structured sales data in Excel, created calculated revenue fields, and used Pivot Tables to analyze top-selling products, sales representatives, regional performance, revenue, AOV, and revenue per customer.

I'm eager to apply my analytical, dashboard design, and data storytelling skills to support data-driven decision-making in a professional environment.
