What I'm looking for

I'm looking for a data analytics or Power BI role where I can build dashboards, automate reporting, analyze business performance, and grow through practical work with data.

I've built Power BI dashboards for pricing intelligence and electronics-store sales, turning operational data into interactive KPI reports and business insights.

In a pricing intelligence project, I compared product prices across online marketplaces and physical stores. My analysis identified pricing gaps by category and supplier negotiation opportunities that could improve margins by up to 30%.

For an electronics store sales dashboard, I developed a Star Schema model, Power Query ETL processes, and optimized DAX measures. This reduced dashboard load time by approximately 25% and automated reporting to reduce manual effort by approximately 70%.

I work with Power BI, DAX, Power Query, SQL, Python, Excel, and data modeling to create reliable self-service analytics. My Systems Analysis and Development degree also gave me a foundation in relational databases, data processing, REST APIs, and Django backend development.
