Most analysts hand you a dashboard and walk away. I build the system behind it — proving that the best data work happens when you deeply understand the domain you're measuring.

My work spans the full analytics lifecycle: ingesting messy datasets, engineering ETL pipelines, building predictive models, and delivering executive-ready dashboards across Tableau, Power BI, Python, SQL, and Excel.

My edge comes from an unconventional path. 25 years coaching elite athletes built instincts most analysts never develop. I know which metrics actually move outcomes, and how to translate complex findings for non-technical leaders.
