Start with the decision
Understand what would change someone’s mind, then work backwards to the evidence required.
About
Analyst, strategist, communicator.
I bridge the gap between raw data and the decisions that shape products, teams, and businesses.
I'm a Senior Data Analyst with a focus on making analytics useful — not just accurate. The best analysis is the one that changes how someone thinks or what they do next.
My work spans metric design, experimentation, dashboard development, and the less glamorous but essential craft of ensuring data is trustworthy before anyone acts on it.

Approach
How I approach analysis
Trust is a feature of data
Accuracy without credibility is noise. Documentation and lineage earn the right to influence.
Simple beats clever
The best analysis is the one a stakeholder can explain to someone else in one sentence.
Show the uncertainty
Ranges, confidence, and assumptions belong in the deliverable — not buried in a footnote.
