What I'm looking for

I'm looking to apply SQL, dashboards, statistical reasoning, and clear communication to help an organization make data-informed business decisions.

I've led analytics engagements for healthcare, digital media, and nonprofit organizations, turning business questions into practical recommendations using SQL, Excel, Tableau, Power BI, Python, and AI-assisted workflows.

For a speech therapy practice, I analyzed 18 months of appointment, payment, insurance claims, and attendance data, recovered $6,000 in outstanding funds, and supported a payer-mix shift that contributed to a 15% revenue increase over six months.

I also bring a Master's degree in Mathematics and years of teaching statistics, helping me communicate quantitative findings clearly through dashboards, reports, and executive-ready presentations.
