Data-driven sales and finance professional translating analytics into compliant tax refunds and measurable business growth.
What I'm looking for
I’m a Sales and Use Tax Consultant who turns large datasets into compliant, high-impact outcomes. At Ryan LLC, I reconciled and analyzed financial data to uncover $500K+ in tax refund opportunities, supported audit documentation, and helped drive a 90%+ approval rate through accurate verification.
Previously, as an Assistant Operations Manager at Hampton Inn and Suites at CSUS, I built data-driven forecasting systems that reduced stock-outs by 25%, improved lead times by 10%, and boosted on-time delivery by 20%. I also led market and competitor trend analysis to support decisions that increased sales by 30% YoY and achieved the highest Customer Experience NPS score (75) in 2022—pairing P&L analysis with customer-focused execution.
