What I'm looking for

I’m seeking a data analyst role using Excel, SQL, Power BI and Python to deliver actionable insights, optimize costs, and support data-driven decisions within collaborative, growth-oriented teams.

I am a results-driven data analyst with strong expertise in Excel, SQL, Power BI, and Python, committed to turning raw data into clear, actionable insights that drive business decisions.

At Viathan Engineering I streamlined reporting, maintained hourly and daily generator performance reports with 100% accuracy, diagnosed root causes of shutdowns, and delivered recommendations that reduced downtime and optimized output.

My project work includes building an advanced Fleet Management Dashboard (295+ drives, 92K+ shipments, $485M revenue) that automated reporting and saved 30+ hours/month, and developing Sales & Profit Analysis dashboards for B&J Biscuits ($61.6M revenue) that revealed profitability drivers and guided promotional and rep-training strategies.

I combine technical skills (Excel, Power Query, VBA, Power BI, PostgreSQL, Python) with a focus on KPI-driven storytelling, cost optimization, and collaboration to help teams make measurable, data-backed improvements.
