Work
Systems built around money, risk and machine decisions.
Each project below states its status plainly. Production work is anonymised where required; prototypes, benchmarks and reference implementations are labelled as such rather than dressed up as deployed systems.
Multi-Processor Payment Reconciliation
Transactions, settlements, refunds, fees and payment events from multiple processors normalised into one auditable ledger with automated matching and an exception queue.
Failed Payment Recovery Engine
Failed recurring payments handled by failure type — classification, configurable retry strategies, customer notification and escalation instead of one blunt retry schedule.
90-Day Cash Flow Engine
Cash-position modelling, 90-day forecasting, scenario simulation, runway monitoring and threshold alerts built on operational financial data.
AI Evaluation Harness
Reproducible datasets, repeatable runs, model comparison, metric tracking and explicit decision thresholds — the difference between an impressive demo and a shippable decision.
iOS Risk Data Foundry
Risk-data collection and pipeline infrastructure, with a reproducible feature-engineering benchmark on a public fraud dataset.
