Product portfolio risk summary

Credit analysts don’t get to ship a wrong number

A consumer-banking star schema — customers, accounts, transactions, applications, and monthly delinquency snapshots — with planted risk-reporting traps: reversals that inflate raw spend, customer-vs-account grain gotchas, charged-off accounts still posting recoveries, FICO-at-origination vs current, and banking-day vs calendar-day conventions.

Query a consumer-banking data model with planted risk-reporting traps, build the vintage curves, roll-rate matrices, fraud rules, and CECL loss projections that credit-risk, fraud, AML, and regulatory teams actually write every month. Shaped around the Capital One / JPM / BofA analyst interview loop and the work mandated by CCAR, CECL, BSA, and SR 11-7.

Vintage analysis, roll rates, delinquency bucketing, FICO-band segmentation, and PD/LGD/EAD feature engineering — the queries every credit analyst writes.

Credit Risk Mechanics

Velocity features, structuring detection, rolling-window rules, and composite risk scoring — patterned on NICE Actimize / SAS AML / FICO Falcon workflows.

Fraud + AML Patterns

Point-in-time quarter-end snapshots, Y-9C / Call-Report-style aggregations, CECL lifetime-loss projection, and PSI / KS model-monitoring queries.

Regulatory Reporting

Every mission maps to a live Cap One Power Day prompt, a JPM Analyst Development Program case, or a Progressive / fintech fraud-strategy scenario.
