What I'm looking for

I’m looking for an analytics role where I can build SQL + Power BI dashboards, track KPIs, and help teams spot bottlenecks and revenue risks fast. I want practical projects that reward clean data, clear storytelling, and continuous improvement.

I am a Google Certified Data Analyst specializing in building automated dashboards that turn messy operational data into clear business decisions. My portfolio (GitHub: Radu-Data) demonstrates my ability to handle large-scale datasets using SQL, Excel, and Power BI.

Key Projects & Impact:

Logistics Performance: Analyzed 100,000+ records in MySQL to surface the "why" behind an 8.1% late delivery rate, mapping failures across 26 states.
Global Revenue Suite: Built a DAX-powered dashboard in Power Pivot to assess $1B+ in historical sales, identifying a 42% customer concentration risk.

I am based in Romania and fully optimized for English-speaking, remote-first roles in US, UK, or EU time zones. I focus on SQL efficiency (CTEs, Window Functions) and creating high-impact DAX measures.
