FinTech + Payments
PCI-grade systems that move money safely.
Gateways, merchant services, payouts, risk, reconciliation, and settlement—built for reliability and scale.
What I build
- Payments architecture: gateways, ledgers, settlement, PCI
- Risk & fraud: rules + ML, velocity checks, device signals
- Operations: reconciliation, chargebacks, auditability
- Analytics: BI pipelines, exec dashboards
- Resilience: idempotent APIs, retries, failover
