Selected work

Case studies from growth, payments, customer and market analytics. Each one covers the question, the method, what I found and what changed, with interactive charts you can explore.

The real figures belong to the companies I worked with, so these charts use illustrative data rebuilt from the shape of the real results (values indexed and lightly perturbed), or public data where it exists. Company, client and customer details are never shown.

How I work

1. Frame the decisionWhat will someone do differently depending on the answer?

2. Distrust the dataCheck coverage, definitions and selection effects before any chart.

3. Find the mechanismCohorts, decompositions and counterfactuals rather than before-and-after.

4. Make it testablePre-agreed thresholds and dated tests that could prove me wrong.

5. Ship itPipelines, dashboards and plain-English write-ups people can reuse.
