PEOPLE-FIRST APPROACH.
01 — ABOUT
Behind every payment,
there’s a person.
Good risk decisions protect both the business and the people it serves.
Across 15+ years in customer operations and fraud risk, I’ve worked across merchant, acquirer, issuer, and customer environments. My focus is finding the patterns behind payment fraud, strengthening detection, and protecting legitimate transactions.
I care just as much about making those findings useful to clients, colleagues, and senior leaders. I’m at my best where analytical investigation, risk judgement, and collaboration meet.

HOW I WORK
From signal to action.
01 Investigate +
Use transaction analysis to understand patterns, segment risk, and identify what needs closer attention.
02 Design & test +
Translate findings into targeted detection rules. Test control behaviour and consider the effect on legitimate customers.
03 Monitor & refine +
Review fraud, chargeback and approval trends after deployment. Tune controls as behaviour changes.
04 Align & lead +
Turn analysis into clear recommendations, partner across teams, and coach analysts to exercise sound judgement.
02 — SELECTED WORK

Data definitions, methodology & monthly values
This interactive demonstration uses generated data, not client data or personal performance results. Transaction country represents the merchant-reported customer country; card BIN country represents the card issuer’s country. They may differ without indicating fraud.
Approval rate = approved attempts ÷ total attempts. Reject rate = rejected attempts ÷ total attempts; this simplified dataset contains only these two final decisions, so they sum to 100%. All approved attempts are assumed settled. Chargeback rate = chargeback count ÷ settled count for the same transaction cohort, using assumed mature outcomes. This is not a card-scheme monitoring ratio. Volume counts attempts, including potential retries, rather than unique customers or orders.
Fraud count and amount describe confirmed outcomes on approved transactions. Rejected attempts are not labelled as prevented fraud. Each matched attempt is assigned one primary rule to avoid double counting; production rule hits can overlap. Aggregated rates are calculated from summed counts, not averaged percentages. The map is illustrative and uses Natural Earth boundaries.
