About Me

Most businesses are not short on data. They are short on answers. I close that gap, taking what is already sitting in your spreadsheets, databases, and reports and turning it into something that actually tells you what to do next.

I'm a freelance data analyst with a BS in Computer Science, skilled in SQL, Tableau, and Excel. My work is straightforward: take raw, messy data, find what it is actually saying, and translate that into decisions a business can act on.

+
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

What sets me apart is not just technical skill. I bring seven years of operational experience inside a real business environment, tracking inventory data, reconciling records, and maintaining a 99% accuracy rate across high-volume daily workflows. That ground-level experience means I understand how businesses actually run, and it makes me a sharper analyst for the businesses I serve.
