What I'm looking for

I'm looking for an entry-level data analyst opportunity where I can apply SQL, Power BI, data modeling, DAX, and Row-Level Security while rapidly developing through real business projects.

I built advanced SQL and Power BI business projects independently, including Northwind Traders commercial sales analysis and an HR employee attrition dashboard.

For Northwind Traders, I created a complete Star Schema data model from an ERP relational database, wrote SQL queries with INNER JOIN and GROUP BY, and developed DAX measures for year-over-year sales comparisons.

In my HR Analytics project, I designed an interactive employee turnover dashboard, implemented Row-Level Security by department, and used SWITCH TRUE logic for dynamic tenure segmentation.

Alongside my data analytics study, I've coordinated onboarding and monitored order-fulfillment KPIs at McDonald's, and I currently process financial transactions accurately in a fast-paced retail environment.
