About Me

Some businesses have dashboards. Some have spreadsheets. Most still cannot answer their most important questions. I help them change that.

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.

+
SQL Querying and Data Cleaning

I extract, validate, and transform datasets of 10,000 to 15,000+ records, building clean, analysis-ready foundations from raw operational data.

+
Dashboard Development and KPI Reporting

I design interactive Tableau dashboards and structured Excel reports that give stakeholders a real-time view of what is working and what is not.

+
Exploratory Data Analysis

I conduct structured EDA to surface trends, performance gaps, and anomalies that would otherwise stay buried in a spreadsheet.

+
Data Storytelling

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.
