Clearer payment journeys.
Exploring how better visibility and handoffs can support payment operations and customer outcomes.
GLOBAL COMMERCE. HUMAN JUDGEMENT.
I’m Yong Shang. I turn payment data into practical fraud controls, clear decisions, and better customer experiences.
Open to leadership roles & consulting conversations

01 — ABOUT
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
Use transaction analysis to understand patterns, segment risk, and identify what needs closer attention.
Translate findings into targeted detection rules. Test control behaviour and consider the effect on legitimate customers.
Review fraud, chargeback and approval trends after deployment. Tune controls as behaviour changes.
Turn analytical insights into clear recommendations and practical, repeatable frameworks that teams can apply consistently. Partner across teams and coach analysts to exercise sound judgement.
02 — SELECTED WORK
I build frameworks and repeatable processes that keep improving after the immediate problem is solved.
03 — PROJECTS & IDEAS
A space for ideas I’m developing across payments, risk, product operations and process enhancement.
Concepts and practical explorations are in development. I’ll share them here as they take shape.
Exploring how better visibility and handoffs can support payment operations and customer outcomes.
Exploring how evidence, monitoring and clear ownership can strengthen everyday risk decisions.
Exploring how operational insights can inform product improvements and team readiness.
Exploring ways to simplify workflows, reduce repeated work and make improvements last.
04 — THE ANALYTICS LAB
Explore payment decisions, risk signals and transaction patterns across markets. Every view responds to your filters.
Fraud outcomes are separate from rule hits. All amounts are illustrative USD equivalents.
Ranked by payment attempts within your filters. Select a country to explore it; headline metrics cover the full selection.
Compare matched attempts, decisions and observed fraud. Select a rule for interpretation.
Issuer-country distribution for the filtered transactions. Select a country to explore it.
Ranked by confirmed fraud amount within your filters. Headline fraud totals cover the full selection.
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.
