Jeffrey Greene | Growth Analytics Portfolio
I turn customer and performance data into growth decisions — dashboards, experiments, and lifecycle strategies that drive measurable lift.
I’ve spent 15+ years leading teams where results weren’t theoretical. Now I bring that same accountability to analytics—using SQL, Python, Tableau, Power BI, and some R to turn messy data into clear actions leaders can actually execute.

How I work
I start with the business decision and define success like an adult: one primary KPI, a few supporting metrics, and guardrails so we don’t “win” by breaking something else. Then I build the data foundation in SQL, validate it, analyze in Python (and R when it’s the right tool), and operationalize the output in a dashboard and playbook that someone can actually run week to week.

Featured case studies
Built to be used, not admired. Each one ends with a recommendation, measurement plan, and proof artifacts.
