I am a freelance data analyst skilled in SQL, Tableau, and Excel. I transform raw data into clear business insights, interactive dashboards, and KPI reports that help businesses stop guessing and start deciding.
I extract, validate, and transform datasets of 10,000 to 15,000+ records, building clean, analysis-ready foundations from raw operational data.
I design interactive Tableau dashboards and structured Excel reports that give stakeholders a real-time view of what is working and what is not.
I conduct structured EDA to surface trends, performance gaps, and anomalies that would otherwise stay buried in a spreadsheet.
I do not just present findings. I build the narrative around them, because insights that cannot be communicated clearly do not drive change.
What Sets Me Apart
Most analysts come from a purely academic background. I bring seven years of operational experience working in a real business environment, tracking inventory data, working with warehouse management systems, and maintaining a 99% accuracy rate across high-volume daily workflows. My operational background helps me understand how businesses actually run, making me a better analyst for the businesses I serve.
